    @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.

    @O2 I ordered a new phone on Monday, I was supposed to receive it on Tuesday. No one from @DPDgroup_news has showed up yet, I called yesterday morning and they said they delivered my parcel TO THE WRONG ADDRESS, never heard from them again

  • ponytail1969 John Patman (@ponytail1969) reported

    @O2 Why is the signal so poor in the Uk.. Sitting in Harwich with a supposed 4G signal, but no internet connection…. So annoying as once I land in Holland in the morning I’ll be on 5G but don’t get to use my data in hindered…

  • camjeffers camjeffers (@camjeffers) reported

    @DannyK67 @O2 I have the same issue and it’s all I see on Twitter they clearly know they have a problem

  • glosfox Jason Keates (@glosfox) reported

    @O2 What is the problem with the voicemail and contacting you on 202? Can't access voicemail or call 202 as the call gets disconnected straight away. I have voicemails I cannot access. Seems a common problem looking at your website.

  • bluegaschris chris fear (@bluegaschris) reported

    @O2 When I wasn’t with o2 and had signal

  • Caitlinquinn91 CQ (@Caitlinquinn91) reported

    @O2 hi, ever since I changed to o2 in the spring, my signal never works & my internet is never connecting. How do I go about cancelling my contract? It really is getting impossible to use my phone. I never had this bother before with another network. Thanks

    @O2 #TBT when o2 actually had service that isn’t useless.
