  • jasonmackenzie Jason MacKenzie (@jasonmackenzie) reported from London Colney, England

    Is there a hashtag for awful customer service from @O2 and/or @DHLParcelUK ? Asking for a friend.

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    Idk what's going on with @O2 signal atm, but for the last few weeks I have no data signal around Crystal Palace at all. Doesn't come back till I get down to Sydenham. Weird

  • ksjsowhat fiono (@ksjsowhat) reported from Barnet, England

    @O2 I made an order on the 27th of October and it’s still not in process, I absolutely need the phone I ordered within two weeks, could you help me please ?

  • electriccandles ⚡️Emma⚡️ (@electriccandles) reported from London, England

    @O2 I've tried all that already. If I had WiFi access I wouldn't need the data to work. Phone signal works fine, just can't use anything with Internet. It's been like this for at least a month.

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @tomlister @O2 @O2 reception in Bath is absolutely appalling. Had same issue all week long when was working at theatre there couple of weeks ago. Similar issue following week in Manchester.

  • CCTVinCare 💜💚Care Campaign For The Vulnerable💚💜 (@CCTVinCare) reported from Gerrards Cross, England

    @O2 amazing customer service experience on your 202 called MARCO. 🙏

  • Atanvarne ㄥ乇乂丨乇 (@Atanvarne) reported from Broxbourne District, England

    @O2 That’s it. They thought that 7am was a decent time to call a customer, even without knowing that I work shifts and was working late last night. 9am I’d have considered acceptable. I wouldn’t have liked it but 9am is REASONABLE. 7am is absolutely NOT.

  • lordshaun_ Lord Shaun O’Brien 🇺🇦 (@lordshaun_) reported from London Colney, England

    The customer service of @O2 is truly one of the worst I’ve ever come across. They tell me to call, but I can’t because they’ve cut off my phone. The number goes through to a bot. Quelle surprise! I paid the bill, as always, and yet here we are. Been on the chat thing for four hrs

  • davidluxton99 David Luxton (@davidluxton99) reported from London Colney, England

    Disappointing poor customer service from @dhlexpressuk who inform me of my parcel delivery at 10.40 this morning then send another message to inform me it will now be 6 days later! #DHL not fit for purpose as a #courier for @O2 as I will now cancel the order

  • shazzstevo Sharon Stephenson (@shazzstevo) reported from Enfield Lock, England

    @O2 My calls keeps dropping. This has been happening for several days now. This is really poor service. This is in the Enfield area

  • peterives50 Peter Ives (@peterives50) reported from Enfield Lock, England

    @O2 Happy Monday to everyone but O2 who still can't sort out my text and calls problems after at least a month 😡

  • frenguin 🐧 Frankie. (@frenguin) reported

    @O2 @roxannehamilton I have had the same problem; paid for Saturday morning delivery and nothing. Shocking service. CS via DM is slow and phone lines are far worse.

  • clairesearles1 Claire Searles (@clairesearles1) reported

    So disappointed in @O2. I have been a loyal customer for over 15 years and I cannot believe you cannot do anything to help me upgrade early. #o2mobile #o2upgrade

  • robyn_xx Robyn Spalding (@robyn_xx) reported

    @O2 Hi, I put my phone to be recycled yesterday & never received any confirmation or my postage label. Tried to do it again, but it's now saying my order number for an extra £150 isn't valid. I've tried logging into my account, but nothing shows. Can someone help?

  • 4kryingoutloud 4kryingoutloud (@4kryingoutloud) reported

    @O2 why is the speed on 4G so bad in many parts of #Warrington Cheshire. I've reported it and for months told "you're aware"....

  • Vernia 🇬🇧Julia Stephenson WarOnWoke VoteReformParty🇬🇧 (@Vernia) reported

    @O2 I have been trying to activate my sim all morning. I’ve called O2 but nobody is replying. I will DM but will have to return to @Plusnet if I can’t get any service. It’s a bit more but they do have customer service.

  • imRazorRamoan Mr. K (@imRazorRamoan) reported

    @O2 pathetic company who couldn’t give a flying **** about their policies and think I’m going to carry on paying! **** right off
