  • 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

  • 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

  • Stefan_baisden Delboybaisden 📸🎥 (@Stefan_baisden) reported from Southall, England

    @O2 has GENUINELY the worst Phone line #Customerservice system ever. I've never been more infuriated just waiting to give a password or speak to someone. Please #O2 update your system to 2019 standard asap.

  • SequinSte Stephen ♏️🏳️‍🌈 (@SequinSte) reported from Barkham, England

    @O2 your website is broken for ordering. I can’t order an I watch 🤬

  • 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!

  • 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!

  • 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

  • RobertBlevin Robert Blevin (@RobertBlevin) reported from Guildford, England

    Hey @O2 - I’ve had appalling voice and data reception for months. I spoke to your shop in Guildford 2 weeks ago, and they said that it was a known issue + signed me up for text alerts. Now you text me every few days to say you haven’t fixed it. 1/2 ...

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    Having an issue this week where Monzo are blocking me from paying my phone bill on @O2 app and website and now seen @BBCWatchdog talking about @monzo and their customers suffering from randomly blocked and closed accounts. #WhatsGoingOnzoMonzo #concerned

  • 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..!

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

    @O2 I love @ O2 Customer Service

  • 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

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @inoobkilervip @craigglawson @O2 @BBCWatchdog @monzo It will if dont pay it soon haha. Will attempt to speak to an @O2 customer adviser tomorrow and pay over the phone and hopefully that will work

  • ZoeThomas1204 VOTE (@ZoeThomas1204) reported from Guildford, England

    I have consistently had issues with the SIM on my phone from @O2 and now there’s no service and I had to go to the store and request help from associates but instead I got a confused and clueless employee who seemed more interested in their snapchats and texts than helping me.

  • 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!

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • ANDREW0675 Andrew Leason (@ANDREW0675) reported from Woodley, England

    @O2 Yeah about those LOL up to end of last year I had no issues at all getting the weekly free hot drink at Cafe Nero while this year I think I have been able to get it only once or twice as always been out of stock both days 😫😂

  • daktadre Dré (@daktadre) reported from Spelthorne District, England

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

  • Flapper_Kirby David Kirby (@Flapper_Kirby) reported

    @O2 is there any chance you can sort your coverage in the EN4 area? It is absolutely shocking still! You are more than happy to increase bills but your service is awful. Please don’t respond with the standard reply and ask if I have access to WIFI again.

  • davidmill93 Davidmill93 (@davidmill93) reported

    @O2 can you help me get into my account

  • kpincott76 Kirsty (@kpincott76) reported

  • oraclecc Axe (@oraclecc) reported

    hi @O2, i need your help with top up. i have recharge code but i can’t reach +441753552277.

  • PettmanCarl Carl Pettman (@PettmanCarl) reported

    @O2 if you don’t want honest answers to your surveys don’t send them, then have someone waste my time on the phone asking why I scored you down. FFS!

  • londontoboston London to Boston (@londontoboston) reported

    @O2 hello the o2 priority cafe Nero app was not valid for the pistachio latte even though it’s in the terms and conditions - I wasn’t able to redeem - please help

  • Huzy242 H u z y (@Huzy242) reported

  • michaellockie Mike Lockie (@michaellockie) reported

    @O2 I’m at cafe Nero and your free coffee voucher is not working. Same for the guy ahead of me. Now it will expire! Can you help?

  • simsjamie Jamie Sims (@simsjamie) reported

    @O2 it's ridiculous and embarrassing that your only option for reaching out for support with your priority app for a silly problem is to publically tweet you.

  • shivandrews Siobhan Andrews (@shivandrews) reported

    @O2 how do I get a refund as Caffe Nero wouldn't accept priority code despite using it as stated in T&C, awful service
