  • 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.

  • 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

  • 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

  • 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

  • VictoriamariaC Victoria Clarke (@VictoriamariaC) reported from Walthamstow, England

    @O2 please can I ask why you have left a 76 women who has just lost her husband and undergoing cancer treatment without any phone service and no one is able to help. Absolute disgrace @lec1479

  • 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.

  • Pretty_Gorge A dollop of kindness (@Pretty_Gorge) reported from London Colney, England

    @O2 on your live chat for 15mins about fraudulent activity on my mobile account. Can someone help?!?!?!

  • 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

  • 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.

  • Big_city_bright MetaDon (@Big_city_bright) reported

    @M_R_Hoffman @O2 Awful, today was the last straw. 2 weeks of incompetence. The app doesn't work. The website doesn't work. False advertisement. The store doesn't know what a rolling plan is. Stay away and save yourself some time and frustration.

  • AndrewBates365 Andrew Bates (@AndrewBates365) reported

    @O2 @virginmedia @ollymurs Still waiting for a call back or a answer to my e-mails nearly 1 week back. RE- Poor continuous service.

  • Oldskoolteach Vicky (@Oldskoolteach) reported

    @O2 Could really do with speaking to someone to sort out why I can’t receive verification codes since moving from EE. Seems you’ve known about this issue for months but haven’t done anything about it! May need to end my contract as I’m still in the 14 days cool off period.

  • Gareth53178094 Gareth (@Gareth53178094) reported

    @O2 @virginmedia @ollymurs So O2 why do you ignore my DM’s to you for the poor treatment to your customers with PTSD. Really poor service

  • crossland92 Samuel Crossland (@crossland92) reported

    @O2 still waiting on a reply regarding the SIM I ordered last Wednesday and now your live chat is down?

  • Kymberley__M Kymberley Murray 🍊 (@Kymberley__M) reported

    Contacted @O2 after trying to move my old number to my new sim for 4 days, only for them to tell me they've been having problems transferring numbers recently and can't tell me when it'll be resolved, thanks for leaving me unable to receive/send calls or texts. Excellent service

  • Nacnan1873 Nacnan (@Nacnan1873) reported

    @O2 How do I cancel an order?

  • robjtweets Rob Jane (@robjtweets) reported

    @O2 - you are the 7th circle of hell. PAC transfer from EE not working. Number lost. Pointless customer service, never resolve any queries, endless hold times. If the PAC system isn't working why are you processing transfers? Why did I leave @EE !!??Contacting ombudsman.

  • HannahTanner84 Hannah Clare (@HannahTanner84) reported

    @O2 Yep, all payments up to date. Signal appears to be fine. Phone is working as much as I can tell.

  • NettyStride Ginette Stride (@NettyStride) reported

    @O2 why did my refund for Apple Watch cover apparently go onto my O2 account, rather than back into bank & this months payment that you had twice take up to 7 days to be repaid to me!! Close to losing a customer
