  • 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

  • MANLIKENAIJA NAIJA BOI (@MANLIKENAIJA) reported from London Colney, England

    @O2 worst bloody network on the planet 6 FREAKING MONTHS I HAVE NOT BEEN ABLE TO USE MY PHONELINE DIE TO A MAST PROBLEM AND I AM STILL FORCED TO PAY FOR IT AND THEN HAVE TO PAY FOR ANOTHER NETWORK SIM JUST TO STAY AFLOAT KMT NEVER AGAIN

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    1/2 BEWARE everyone considering switching to @O2 They offer to port your existing number from your previous provider, which is really important to many, but FAIL miserably, when you call customer services multiple times, they promise a 4 hour resolution, this never happens..cont

  • 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

  • MattGauntlett Matt Gauntlett (@MattGauntlett) reported from Watford, England

    @O2 I need help ASAP 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.

  • Jennifer03017 Jennifer Ferguson (@Jennifer03017) reported from London, England

    @O2 when you press use now on the Priority Lane where is the code - I only have a screen with a timer counting down. I can’t see a code? Thank you xx

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

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

  • 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.

  • garywebbTHFC Gary Webb (@garywebbTHFC) reported from St. Stephen, England

    2/2 @O2 promise to call you back, but as yet nothing, they promise to escalate to a manager, but surprise they don’t call you back either, their Twitter also ignores your serious concerns.Think seriously before choosing @o2 if there’s an issue THEY don’t seem to care! @VMO2News

  • 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.

  • placid_casual placid (@placid_casual) reported

    @O2 Your customer service is utterly shambolic - trying to sort a new sim out for my son on his holiday had his phone stolen.

  • DaveSimon10 Dave Simon (@DaveSimon10) reported

    @O2 does not cover 65% off Blackpool. Yet a contract is sold in Blackpool they do not say. & if you complain after the fact they lie & say “there is a problem with a mast and our engineers are working on it now” they say same thing for 4+ years @itvMLshow @paullewismoney

  • richardbeany richard hines (@richardbeany) reported

    Hey @O2 surely there should be money off our bills seen as there ain’t hardly a service we are paying for???

  • elgobsucram Marcus 🇬🇧🇯🇲🇮🇪🏳️‍🌈🇪🇺✊🏾 (@elgobsucram) reported

    Is it even remotely possible for @O2 to maintain a signal?

  • PowellVerity Verity Powell (@PowellVerity) reported from Spelthorne District, England

    @O2 worst customer services, ring 202 to pay off phone and they cut me off then don’t answer, told on chat to follow link to chat to someone else who tells me they can’t help and ring 202! Going round in circles no wonder once paid off phone I’m leaving!

  • johngonoud2 Johnny Boy 2660 (@johngonoud2) reported

    @AncientKeeper @EnglandRugby @O2 I do get your point Simon to be fair & can only assume it’s down to Jones favouring DCs experience on the day especially in first 60 mins.

  • Deep_diver_uk Paul (@Deep_diver_uk) reported

    @O2 @virginmedia hi how long does it take to reply to DM ( can I cancel sim contract if can’t get/receive calls at home and told it’s a mast Issue 3 months still not working CR2area)!!!

  • danielwhitehead Daniel Whitehead (@danielwhitehead) reported

    @WaynePearson63 @EnglandRugby @O2 Wonderful match and a crazily great player but (a) not a bad idea to deflate his balloon a bit (b) EJ will want to know if DC can get more about of Smith (c) will be glorious to see a fully motivated JvP running at tired legs …

  • Lawilliams88 Levvis (@Lawilliams88) reported

    @EnglandRugby @O2 Christ, Hill is slow. It continues to blow my mind how he is repeatedly rated and picked.

  • markcottle17 Mark Cottle (@markcottle17) reported
