    @O2 I’m trying to buy a new phone - still on O2. Deals are better than you’ve offered me to upgrade through my account. I only want a PAC code but as I have my sons phone with O2 it seems very complicated! One hour still holding - dreadful customer experience

  • runray2000 Johnnie Ray (@runray2000) reported

    @O2 taking 3 days to port a number for a straight o2 to o2 swap. Keep being told 24 hours, now to wait longer. Nobody seems to have a clue. Can someone help? Not good enough and being fobbed off.

  • JudgeDewie Alex (@JudgeDewie) reported

    @garyfranklin @O2 I complained to them about the fact we no longer get 4G in our area only 3G. Neighbours say the same. Builders who were here last week say the same. O2 maintain service is fine but won’t send someone out to check it. Complained. They said they will let me out of my contract early

    @O2 I dont feel this way! I experience this way! Whats happening to justify the amount people pay you for the shoddy service and signal problems? The issue is at your side not mine…

  • GoodForUsAll Peter (@GoodForUsAll) reported

    @O2 Hello. I signed up for a 12 month SIM only contract recently through uSwitch but have since seen another deal I prefer. Am I best just to cancel my current deal (I'm still within 14 days) and sign up to the new one or can I do some sort of switch? Thanks.

  • MichelleCarr91 Michelle Carr (@MichelleCarr91) reported

    @O2 your customer service this morning has been absolutely awful and I would appreciate someone getting in touch

  • JovanaTalks Jovana (@JovanaTalks) reported

    @O2 Thanks, turns out there’s an issue with one of the masts in the area, service is still temperamental but it’s better than it was #progress

  • Whitey4K_ Whitey🤙🏻 (@Whitey4K_) reported

    Seriously can’t wait for Friday, moving back over to @EE after 3 years of poor service/internet on @O2 will be refreshing.

  • DomLip94 Dominic Lipscombe (@DomLip94) reported
