    @O2 the mast in HD9 4AP is not working again. This is the 3rd time in January! This is an ongoing problem and you can continue to ignore it (and me) but I will not be renewing when my contract comes up and nor will many others. Your network is just too unreliable.

  • DomMog86 T (@DomMog86) reported

    @O2 Hi, my nearly 6 month old S22 keeps dropping signal during calls resulting in robotic voice, stuttering, long silent periods during a call. This has been happening for a while. Any suggestions on how to fix this? Thanks.

    @virginmedia Hi John, Not really a "Team" though is it!? One of your "Team" told me yesterday i couldn't lower my service tariff. Today i was informed again by your "Team" that i couldn't lower it, but i could cancel it. Followed by a brief sales pitch of @O2 No thanks.

    @o2 Hi - the signal coverage for data in paddock wood inside & outdoors is poor to unusable. Additionally, response time in London for data is v slow. Are any improvements in the pipeline? Pls persuade me why I shouldn’t move elsewhere.

    @O2 Your customer service team is shocking. Trying to submit an insurance claim on an iPad that’s died through no fault of my own. First I’m told that because I can’t power on the device and get the IMEI I have to wait for this to come via email by the end of today….
