  • 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 .

  • 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

  • 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

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • 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

  • 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.

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

    @O2 very poor customer services fuming is an understatement 😡

  • 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

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

    @O2 I love @ O2 Customer Service

  • DamianPDavis Damian Davis (@DamianPDavis) reported from Spelthorne District, England

    @paddyguy51 @Ker_Anderson @Phonemast Do your self a favour and swap to a network that actually works, i.e. anyone but @O2

  • 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

  • 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

  • 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. 👍

  • 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

  • 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

  • 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..!

  • timlimbim Tim Cawte (@timlimbim) reported from Maidenhead, England

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

  • sarah_lou_ise_ Sarah Louise ♡ (@sarah_lou_ise_) reported

    @O2 I know for a fact that is not true, as my partner had the same issue (mast issue that only can’t to light when she reported it multiple times) August and you credited her.

  • smart86y Tom Smart 💙 #stayhomesavelives #savetheNHS💙 (@smart86y) reported

    @O2 This doesn't cover it, myself and wife have tried all the options, and it's clear that we aren't the only ones having problems based on the Twitter feed

  • TheOnlyAlisonL Alison (@TheOnlyAlisonL) reported

    @O2 Thanks. When is best to cancel? Have I paid for this month? If I cancel now does it end instantly? Etc.

  • TheOnlyAlisonL Alison (@TheOnlyAlisonL) reported

    @O2 Hi, My bill landed today with Disney+ included as a bolt on. I wish to cancel this service before the price hike on 23rd August when do I remove the bolt on? (i.e. have I already payed for this months subscription?) and can I do it easily via my online account or via the app?

  • Ant_lee Anthony Lee (@Ant_lee) reported

    @O2 please can you help with this? Need to know whether this is something that needs to be done by me or because I submitted when purchasing my new sim only deal there is further action needed.

  • robathersmith74 Rob Athersmith (@robathersmith74) reported

    @O2 yet again poor or no signal in the DT3 6A area! Absolute joke I can’t wait to bin you off. Me take my money elsewhere! 😡😡😡😡😡😡😡😡

  • gwsdeviI soph♡☁️| 🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@gwsdeviI) reported

    @O2 im ready to leave o2 the customer service is shocking and the service itself

  • TheWonderHorse1 TheWonderHorse (@TheWonderHorse1) reported

    @O2 NOT the quality of customer service usually seen from O2 today! Disappointing... everything seems stacked to prevent actually getting to 'speak' to someone! ... Always when a problem needs resolving!

  • LeeOnPluto Lee🪐 (@LeeOnPluto) reported

    Really curious why @O2 is making it absolute hell for my mum to cancel my recently deceased father’s tariff? Possibly the most insensitive customer service I’ve ever seen in my life. The O2 customer service team should be ashamed of themselves.

  • OfficialPBKR Paul Renner (@OfficialPBKR) reported

    @O2 why is it so hard to speak to your customer service team🤬🤬🤬.. your IVR system is so poor..
