  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • stourdave Dave (@stourdave) reported from London Colney, England

    @O2 How did this shit happen

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • aktyrrell Andy Tyrrell (@aktyrrell) reported from Walthamstow, England

    @harwood_steve @O2 @EE EE service is shit around Chingford guys I work with never get a service I'm o2 never had a problem. Probably the country you're in. Plus we always get upgraded at the o2 by the o2 Angel's.

  • SemperVeritas Nom De Guerre (@SemperVeritas) reported

    @O2 why is there no 5G data in Stratford Westfield? Surely you must have the capacity on your network with all the profits you are making! #CorporateGreed

  • Jmrplus4Jane Jane Beesley (@Jmrplus4Jane) reported

  • blockthecoup Madam Day (@blockthecoup) reported

    Hey @O2 Can you tell me how I get access to the O2 Priority area at Forwards Festival in Bristol this weekend please? What do I need to do to prove I'm an O2 customer? Cheers!

  • davidtcfc David (@davidtcfc) reported

    @O2 how bloody hard is it to make contact with customer services. 4 days now and nothing. The new virgin o2 app is as much use as a chocolate teapot

  • ckb0001 Chris B (@ckb0001) reported

    Hey @O2 keep getting problems doing online and phone top ups… do you have any issues or could it be a new account setup issue please?

  • IndicSocietee Adit (@IndicSocietee) reported

    Shambolic service from @virginmedia & @O2. 4 days since raising escalation CIT-A232463 over an e-sim error & I’m still stranded abroad with no mobile connectivity. Your incompetence has left me cut off in a foreign country. Even the worst service providers are outclassing you at this point.

  • CoveViewHoliday Cove View (@CoveViewHoliday) reported

    @O2 Please could you advise? Will #O2 be reducing my bill for the days that my service is being interrupted this month by your local maintenance works? As #O2 will not be providing service on those days, it would be fairer if I don’t pay for the interrupted days #O2down

  • GoonerGrey GoonerGrey ⚽️ (@GoonerGrey) reported

    DO NOT USE @O2 their service is disgusting and they do not help with fraudulent activities on your account. #CustomerService #o2 #badservice
