    Still having signal issues with @O2 - over a week now! Spent half hour on Friday hanging out of a window making a call. Please can you update for LL572NQ - this is causing real issues working from home! You’ve admitted a mast issue, but when will it be resolved please?

    @O2 Thank you for the heads up, the postcode is actually a publicly accessible office where the signal drops out, so not a personal address.

  • KatyLeanne25 Katy P (@KatyLeanne25) reported

    @O2 horrible company! Scammed my husband into a contact with you by promising him you'd retrieve his voicemails of deceased relatives (which was a lie!) Then ruined his credit score (whilst trying to apply for a mortgage) saying he hasn't paid his contract when he cancelled it!

  • mar1a_a Maria Afzal (@mar1a_a) reported

    Hi @O2, I am waiting for a sim to arrive in the post due to having some issues with my current o2 sim. However I am getting sim not provisioned on my phone popping up. I am currently unable to make any calls or send any texts. Please advise? Thanks

  • MissTillyAndMe Miss Tilly And Me (@MissTillyAndMe) reported

    After 20 years I am leaving @O2 because I struggled to pay my bill. When I phoned the customer service to ask for another week. The lady said it would affect my credit reference and there would be a £6 fee. As I am having trouble paying the £26.00 I owe you, don't you think

  • denny57 denny57 (@denny57) reported

    @AXS_UK unable to attend @DianaRoss @O2 last week due to having an operation on my arm. I had insurance and put in a claim for refund they have declined my claim as my insurance was on the original date and not the COVID rescheduled dates! & I need to speak to you for refund HELP
