  • 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 Sort ur crap signal out don’t get internet anywhere in the whole of the uk

  • NickyJ101 Nick Jillings (@NickyJ101) reported

    @O2 unable to log in at all on website or app. When is this being resolved? Log in just times out. App stalls then says unavailable. Pretty slow response for an IT company.

    @EE Absolutely no issues with @O2 in the parts of Liverpool I’ve lived in... only ever heard bad things about @EE in the city too... weird.

    Loss for words yet again @O2 after spending hours on the phone and being promised a refund and credit for the inconvenience YET AGAIN it didn’t happen. any suggestions on a better phone network I can switch to? @CPWTweets thanks to your initial mistake I’m still paying the price

  • mellyjenga1 mellyjenga (@mellyjenga1) reported

    @O2 appalling advice from your shop 18 months ago when I purchased iPhone 11 Pro Max and yet you still charged me over £50 a month on contract. I’ve been with you since you opened so am a loyal long term customer. Will move to Vodafone now #leaveO2 #O2poor #badserviceO2

  • AnneBoydUK anne boyd (@AnneBoydUK) reported

    @O2 pls advise on how I can make a complaint having spent too many hours waiting to receive a response to messages or waiting on a phone line - thanks

  • cajjio Carol Johns_TC (@cajjio) reported

    @O2 I've tried all that before. It's your poor service in this area, get a text once a month saying they will update in another month? 😒

  • skp20040 skp20040 (@skp20040) reported

    @O2 Hi if a message on someones phone says "s emergency calls only" could it be connected with a service issue you have in that area as you have an online status saying "Looks like a nearby phone mast isn’t working as it should, sorry."

  • ShirleyR64 Shirley Rossington (@ShirleyR64) reported

    @O2 I need to pay the final instalment on my device as I have left you due to you constantly putting prices up. You have send me a snottogram about it. You have shut down my o2 account. When i call it says I cannot speak to anybody, I have to use the automated service.
