    @O2 is there a 4g issue in the ct17 9sx area at all? Im getting nothing!

  • terenceclayton7 Terence (@terenceclayton7) reported

    @O2 need to send my phone off to repair but I can't call as that's the issue, can't visit a store and I cannot use your app as it's a maze leading me in circles. Your a telecommunications company who can't even help it's customers 👍

  • simtip Simon Tipper (@simtip) reported

    @virginmedia Broadband is fine, this is regarding being moved to @O2 as part of my package negotiated with retentions. Previous mobile under Oomph package was great now being told that in my two main postcodes the 4G is congested and there's an unknown fix date 1/2

  • CynthiaLarbey Dr Cynthia Larbey (@CynthiaLarbey) reported

    @O2 I know of no company that in this day and age would leave an entire region without phone service for 6 days! What are you playing at? Or don’t you think the people of Arrochar in Scotland are worth bothering with, with their businesses, hydropower schemes, & climate activism.

  • pconnelly1971 Peter Connelly (@pconnelly1971) reported

    @O2 Received my new sim from you today (swapped from vodafone) . Getting a message saying network locked sim inserted . Can you help ?

  • andyroocraig Andy Roo Craig (@andyroocraig) reported

    Dear @O2 I've spent more than a year trying to sort something out with you. I call your staff. They can't help. They say your "specialist" team or similar will contact me. I hear nothing. I get too busy and another month goes by. Please can someone help. Thank you.

    @O2 @SamsungMobile Worst customer service in the world. Tried (called 7x) to cancel sim within 14 days on my partners account (i upg instead), charged 25, told it was canceled, now have a final bill of £395.00, telling us to cancel DD which results in missed payments. WHAT THE HELL IS GOING ON?

  • TracyMagee4 Tracy Magee (@TracyMagee4) reported

    @O2 I am absolutely appalled at o2 customer service. A member of the 'customer service' team hung up when I was trying after 6 hours on the phone to o2 over last 4 weeks to get the service I am paying for it
