    @O2 @pchavda Having to reply from a colleagues phone. Reported this morning at 9 o clock. Still service-less. Bet you’re still charging full rental though.

  • MayaAvidov Maya Avidov (@MayaAvidov) reported

    @O2 Hey @O2 1 message every 24 hours, that repeats the same info you asked previously, with no immediate follow up is not going to solve this problem. Can I please have some actual efficient customer service?

  • mrscassw Cass (@mrscassw) reported

    It’s been 36 days since I reported fraud to @O2 - still getting threatening letters for an account never opened and nothing from the fraud team…..

  • Benrshrimpton Ben shrimpton (@Benrshrimpton) reported

    @O2 I have sent a message. I am more concerned about the GDPR issue as my address had been updated and does not seem to be on my account!

  • helenmc46972890 Helen Mrs Happy (@helenmc46972890) reported

    @O2 I’m having problems with mobile data I be lucky if I get 10 mins a day everything say no internet connection #help #please

  • JElliott_MIC Jonathan Elliott (@JElliott_MIC) reported

    @O2 help. In europe and connected to cosmo on E but no 3g. Roaming is on. Bolt ons bought.

  • JohnoGreig Johno (@JohnoGreig) reported

    @O2 hello, why is it I can get full 4G signal half way up a mountain on a Greek island but here in my home (TS10 4SD) I can’t even load a website with my one bar!

  • simon_r_tucker Simon Tucker (@simon_r_tucker) reported

    @MartinWildlife I was thinking of changing for a better signal but I will stick with @O2 - only please do something about the coverage in rural north Wiltshire. It is poor immediately you leave any of the town's. I appreciate the signal booster in my house but outside it's v. poor.

  • JonMagicman Jon Pepper (@JonMagicman) reported

    @O2 @O2 This is the 7th working day and still no phone call from the complaints team. I've already started to take legal advice on this as it's an open and shut case. A phone call would have gone a long way to resolving this. Such a shame that customer service appears non existent.

  • lozzylols Lauren Treagust (@lozzylols) reported

    Hi @O2 do you still give refunds for loss of signal to your customers? You have been doing work in my area for over a week now and I have had hardly any signal that whole time and it's still not fixed. I can't make calls, access the internet, and I've missed important calls too!

  • AmandaJDee Dr Amanda Dolan (@AmandaJDee) reported

    @O2 Not had a problem roaming with EE in either Spain or USA. Not cost me a penny extra either. O2 coverage just isn’t good enough outside cities to make them worthwhile for the times I’m not on holiday.
