  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • 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.

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • Mattoco Matt O'Connor (@Mattoco) reported from St Albans, England

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • 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

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • fierce_unicorn 🦄 (@fierce_unicorn) reported from Enfield Lock, England

    @O2 merlin pass code is not working, can you help?

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • 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

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • 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

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • 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

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • rsbo Qamar ZK (@rsbo) reported

    @O2 a digital esim swap was done in store for me. And I was told it would be up and running within 24 hours. But nothing. I don’t have any number and no one can help. Please look into it

  • NC20023 Nigel Rob (@NC20023) reported

    @O2 WHY do you find it such a challenge to provide the village of Armthorpe, Doncaster a 4g service in all parts of the village ? Absolutely pathetic !! #Useless

  • debswild DEBS WILD (@debswild) reported

    @virginmedia Yes. There is yet another outage. I've lost count of the times this has happened this year. Perhaps @libertyglobal can shed light? @O2 isn't great either! Making complaints makes no difference. #VirginmediaO2

  • RealHarland Harland Sanders (@RealHarland) reported

    @O2 Total rubbish my phone didn’t have data abroad and you never fixed the problem

  • billtheavtech William Gillingham (@billtheavtech) reported

    @O2 your communication is awful, quit your network ages ago. Now get a bill and your customer service advice on the phone is ‘go to a shop’ the fact that the letter is dated 23rd, arrives on the 27th and yet gives me 5 days?!

  • BellaBrownDog BellaDog (@BellaBrownDog) reported

    @O2 she needs refunding and compensating for the time without service and reimbursing for the phone she has had to buy. After so many attempts to solve the issue it is clear that you can’t and so she should be given a replacement phone 2/2

  • chadissacclark Chad (@chadissacclark) reported

    @O2 My Port In is meant to be happening today. I’ve had no confirmation, no text, nothing to say my number will be switched by 6pm. Can somebody help?

  • UFOHunter64 Trev the avatar (@UFOHunter64) reported

  • riddl4methis gk (@riddl4methis) reported

    @o2 any chance you can train your staff how esims work. Trying to swap my number to a new phone, I am now into my second day with no service.

  • RowanJ10 Rowan (@RowanJ10) reported

    @o2 I contacted customer services on Friday and gave a PAC code so a number port could be initiated. I was told it would be complete by 6pm Monday. I still have no signal - it’s 11:09pm, and have turned the phone on and off many times. Pls help.
