    Wow @O2 honestly cannot believe how poor your service was this evening. Incompetent advisor with seemingly unusable (almost useless) systems. #complaint #poorservice

  • miajohnston1967 Mia Johnston (@miajohnston1967) reported from Bracknell, England

    @O2 very poor customer services fuming is an understatement 😡

  • LyndallAnn Lyndall (@LyndallAnn) reported from Hounslow, England

    @O2 This issue started a few weeks ago for me and my friend has had the same issue so changed phone companies a couple months ago.

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • AikSaath Aik Saath (@AikSaath) reported from Slough, England

    @sabia_hussain @SEGROplc @O2 SEGRO have checked to see if the theft was on the estate itself. We'll see the young people right - just thought it might be worth reaching out to our 'bigger cousins' to see if they could help. Good to hear they didn't find anything in your car. 👍

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • Primrose_Hikwax Primmy💁🏾 (@Primrose_Hikwax) reported from Slough, England

    @O2 There was a mast down in my area but the matter wasn’t resolved for 3 weeks. I have data with EE on my ipad and the data wasn’t affected with them. With my phone I was unable to text, call or use my data. I don’t understand how you expect to put off £11, yet I haven’t been able

  • EmmaEgbers Emma Egbers (@EmmaEgbers) reported from Cobham, England

    @O2 been waiting for nearly a month for my issue to be solved, still NO response from anyone and being charged again, respond immediately

  • B_Heer84 Bari Heer (@B_Heer84) reported from Wraysbury, England

    @O2 are the biggest disgrace possible. Im a pay monthly customer, paying £53 a month. I have no network coverage. O2 have confirmed I live in a Black spot and they will not be helping me. They said to me..’These things happen’...! O2 said I still have to pay my monthly fee..!

  • Iccle_Princess Vger Ann Goldby (@Iccle_Princess) reported from London, England

    Its amazing @O2 can sort out fraud against my 13 year old daughter but @VodafoneUK cant & tell me to go to my local shop with my daughter to prove she didnt take out a contract like wtf!

  • Nick_G6 N I C K 🇿🇼 (@Nick_G6) reported from Hounslow, England

    Dear @o2 and @StarlingBank it’s been two weeks and I still can’t believe that I cannot pay my phone bill via the app! Please send help I’m all out of options here. Now I’m accumulating charges for late payment 🤬🤬🤬

  • smileyyearwood Send News!☝🏾🇧🇧 #StopTheCoup 🌹 (@smileyyearwood) reported from Harrow Weald, England

    I've decided to hang onto my @HuaweiMobileUK P30 Pro until the next gen of 5g phones. Was going to take an @O2 deal but it only shows 4g and says you'll then need to take a new chip and contract for 5G not guaranteed you'll pay the same price. A lot of 1st adopters are screwed.

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • jayblake_ Jay Blake (@jayblake_) reported from Marlow Bottom, England

    Dearest #02 @O2 I do wish all your customer service people were as helpful as the person I spoke to today. Sadly there were several trees killed in the printing of a years mobile bills, which I was told was required. Todays agent simply gave the info I needed in a 5 min call

  • PandaEyesKirsty Kirsty Ann (@PandaEyesKirsty) reported from Maidenhead, England

    @AmazonUK I have made a large order and it has been delivered to a Amazon locker. This locker is in a private @O2 building. THIS WAS NOT STATED AT THE TIME I ORDERED! Now they're refusing me access so my daughters birthday presents are not able to be collected!!😭 HELP!

  • boogieloo Jodie De Vere (@boogieloo) reported from Southall, England

    @O2 I love @ O2 Customer Service

  • BecOz14 Bec Osborne (@BecOz14) reported from Camberley, England

    Have had 1 bar of @O2 signal for most of this year, funnily enough when I tested the signal strength back in July the signal jumped to a MEGA 2 bars momentarily. #NoServiceHere

  • n1spm Sean Meade (@n1spm) reported from High Wycombe, England

    Following a recent mobile roaming incident (connected to a Bosnian network 4.5km+ from Dubrovnik airport), it did make me wonder why phones don’t have tiered roaming settings e.g. within EY, outside EU etc @Apple @o2 #roaming

  • NasiraKasmani Nasira (@NasiraKasmani) reported from Maidenhead, England

    @O2 unbelievable service from the #CustomerService agent today, so rude lady called Ambreen kept speaking over me. Unacceptable that staff have the audacity to speak to customers in such a manner and instead of resolving an issue escalate it to another level. Who do I complain to

  • NeilNutbeam Neil Nutbeam (@NeilNutbeam) reported from Hillingdon, England

    @O2 why is the network and 4g soooooo bad. Well I say 4g, I never get 4g most of the time. And even if it does say 4g it’s rubbish and slow, stuff still doesn’t load. A lot of the time I have to turn 4g off and change it to 3G for it to work. Rubbish

  • Tiffers1973 Tiffers (@Tiffers1973) reported

    @O2 is the myo2 app not working? Keeps telling me it can't help with my type of account?? A pay monthly account

  • TweetFlicker 𝕄𝕒𝕥𝕥 ℂ𝕝𝕒𝕣𝕜𝕖 🎮🕹 (@TweetFlicker) reported

    I’m just outside Peterborough with barely any phone signal & the internet is on 3G…it’s exactly the same around derby city centre too. @O2 this really needs sorting because it’s just not good enough. 3G was always fine before the introduction of 4G & now I can’t use internet.

  • ClaireG60548352 Claire ♡ (@ClaireG60548352) reported

    @O2 priority not working for Paolo Nutini in Edinburgh - been on since 8.50 this morning - is there an issue with the app?

  • KateRoe16 Kate Roe (@KateRoe16) reported

    @roselin42487909 @O2 It’s constantly down at the minute, I’ve had enough!!

  • HMQueenPink Queen of Pink (@HMQueenPink) reported

    Now the council are saying hes noted with credit companies as being at my address (he owed £8 to @O2 🙄🙄🙄) and that I've fraudulently claimed that I lived alone!!! I don't have time or energy to sort out the mess. I will NEVER EVER consider O2: they're consistently atrocious

  • JonnyPianko Jonny Pianko (@JonnyPianko) reported

    @O2 I am in northern Corfu which is very near Albania, yesterday my network changed and I received a text message saying welcome to Albania which isn’t in your eurozone, I should not be charged for roaming there when I never left Greece should I ?

  • louise_marcel Louise M (@louise_marcel) reported

    @O2 my phone still isn’t working properly other than in my front garden. Not very useful. A mast was down but in a city I’d have thought you could sort it quicker than 4 days…

  • HMQueenPink Queen of Pink (@HMQueenPink) reported

    Really really infuriated by @O2 clowns. They screwed up a customers address and used mine. No matter how much I told them it was wrong they refused to investigate and sort out their mistake. They even gave my address to the customer when he called to ask where his post was!!!

  • roselin42487909 roseline morris (@roselin42487909) reported

    @O2 I’ve tried all those and I just got my neighbour to turn their WiFi off and check and they have no signal either

  • Twitsham83 James 🐺 (@Twitsham83) reported

    Hey @O2, is 4G still proper signal or do phones on your network now only work with 5G?! Absolute shambles recently 💩
