    @O2 More than 36 hours into the less than 24 hours to swap my number over to the new sim... still new phone says "no sim" (its in it) old phone stopped virtually instantly. We'll send you a text to verify... cheers O2, i trust you will not charge me for days with no service?

  • Rich25101980 Rich 🇬🇧🏴󠁧󠁢󠁥󠁮󠁧󠁿 (@Rich25101980) reported

    @virginmedia Other people have the same issue with @O2 when in the area… It’s ok I’ll just change network as advised by your staff unless if there’s something that can be done?

  • MikeHewitt07 Mike Hewitt (@MikeHewitt07) reported

    @O2 how come your customer service team don’t have access to accounts? I’ve raised an issue, sent details through and now I’m being asked for screenshots of details…surely they have access to everything on screen or is it a fake customer service email on your website?

  • imcc63 Ian McCabe (@imcc63) reported

    @O2 this service is not working at m24 1RU when will it be fixed

  • BenjaminLappin Benjamin Lappin (@BenjaminLappin) reported

    @O2 I have sent you a DM on this matter. I sincerely hope this gets addressed because there is clearly an issue in store.

  • janerayson Jane Rayson (@janerayson) reported

    @O2 Still no answer. Come on @O2 surely you can offer better service than this!

  • BSIntollerant MindYour Business (@BSIntollerant) reported

    @O2 @NHM_London Priority customers? Please... Existing customers are treated like trash. In order to get the deal i want from you, i have to cancel my current contract with you and get a new one. How disrespectful is that?

  • johndfahy John Fahy ⭐️ (@johndfahy) reported

    @leemc87 @O2 Don’t even bother to try and make a call in North Devon… haven’t had a decent O2 signal in literally years

  • amandalw72 Amanda W 💜🐐 (@amandalw72) reported

    @O2 is there a signal issue in the NN14 area? None or little service since yesterday 🤔

  • lucygar11753113 lucygardner (@lucygar11753113) reported

    @O2 This is ridiculous! I was not told this when I set up my new account, my old email address went through fine. I only have one email address and because of this I’m now not able to see my bills or change anything on my account? This is really bad customer service!
