  • stephenblevins9 Stephen Blevins (@stephenblevins9) reported from Rich Hill, Northern Ireland

    Could someone at @O2 explain why the service in BT61 has been diabolical for almost two weeks? Bit of a nerve advising us of a spike in bills alongside a drop in service? Not exactly sure what I’m paying for at the minute.

    @o2 My phone hadnt been used for a long time. O2 reconnected my number. I just made a call to my phone, which connected. The SIM status, on receiving the call, changed from inactive to active, with the O2 network then showing. How can I make it show as inactive again?

  • joeheys Joe Heys (@joeheys) reported

    @O2 hello I was promised £10 off my next airtime bill as a result of getting zero service for five days on my holiday and that hasn’t happened yet?

  • 5haz2a Sharon Holloway (@5haz2a) reported

    @O2 how do I cancel a SIM within the 14 day cancellation period if I don’t have a my O2 account. I can’t get an account without the sim, but I think the sim may be delayed in the post because of the postal strike, and I can’t wait for it to arrive as it may be over the 14 days

  • ovl_xo 𝓵𝓲𝓿💋 (@ovl_xo) reported
