    @O2 Poor customer experience in-store today. Disappointed to say the least.

  • dartduignan180 sean duignan (@dartduignan180) reported from Culmore, Northern Ireland

    @virginmedia @O2 But not your customer service when it comes to cancelling an order

  • KieranKelly1988 Kieran Kelly (@KieranKelly1988) reported from Derry, Northern Ireland

    Quite shoddy of @O2 to refuse me a contract as a new resident of Northern Ireland when my driving licence is in the Republic of Ireland and not offer an alternative verification or reply to my email of complaint from 6 days ago.

  • RyanF_88 Ryan Foulkes (@RyanF_88) reported

    @O2 This company’s customer service is the worst I’ve ever dealt with. As soon as I get through on the phone I’ll be letting them know I’m off back to EE @O2

  • ChrisMCook Chris Cook (@ChrisMCook) reported

    @O2 are going about the right way of losing a customer of 18 years!! Stop cold calling me with “offers” which are sold as being for a “loyal customer” when any Tom **** or Harry can get them - 🤬

  • SteAndKel Steven (@SteAndKel) reported

    @o2 please sort your **** internet out throughout the U.K.. Can’t ever use ******* data.

  • badassscotsman BigYin😜 (@badassscotsman) reported

    Personally I would stay clear of @oppo and their new phones. Especially with the constant repeated text messages and not receiving data until they sort it out. It's a massive problem they do know about.. @O2 know about the problem but still sell those phones.

  • allieb2121 allieb21 (@allieb2121) reported

    @O2 It won’t let me as it says minimum 6 months but I don’t want it as it doesn’t have what I need and I wanted to know is there a grace period to cancel?

  • amyc5621 Amz (@amyc5621) reported

    @O2 Why can't I access my O2 account?? Tried all options. Still says I am not registered but I am #Help

  • mrtownboy Anand K (@mrtownboy) reported

    @O2 @vikki_reed Disappointed by the @02 customer support team!! #O2 When we send you a private message, the response we get is nothing more than a sentence. It also takes a day or two.

  • vodcal cal (@vodcal) reported

    @O2 still no answer to why I'm charged falsely for things and no improvement on the signal at all. Absolutely useless having a phone most of the time. Should be allowed to come out of contract if you fail to provide a service!! #ripoff #poorcustomerservice

  • iamchrissharp Chris (@iamchrissharp) reported

    @O2 I completed DPA to get this sorted on Saturday, it’s now Tuesday and it’s been over the 24-48 hour mark yet yours now sending the same 24-48 hour message. Please respond without automated messages today, I’ve had such a problem trying to get this tablet returned

  • paulmilham Paul Milham (@paulmilham) reported

    @O2 morning, it’s been a week now since I’ve been able to make or receive calls on my mobile from my home, which is where my office is based in HP22. It’s becoming a real problem. Any updates available please?
