  • CityOfHushHush ✨🌸call me Vee pls🌸✨ (@CityOfHushHush) reported

    @tescomobile @156v6 @O2 I can second that. I've been with Tescos for years (mainly because its a 15 minute walk from my house if I need to speak to someone about my phone) and my contracts have never changed. Even when my contract was finished I was still about to stay on it for a bit until i wanted to-

    @O2 i’ve tweeted and DM’ed you so many times and youre not responding but you’re posting stupid GIFS? i cant even use your online chat cos you’ve blocked it. i cant even call you.

  • DianeM176 Diane Marie Taylor (@DianeM176) reported

    When my stupid contract is up I’ll definitely be leaving @O2 I only wish I had enough money to pay it all off now & be shot of them 😡

  • Nutley88 Neil HTID Nutley (@Nutley88) reported

    @O2 please sort out you're network, no matter where I go when I pull up for break l, I have 4g signal but the network is unstable! It happens everywhere I go. Dangerously close to changing network provider because of this!

  • CaitlinClappis1 Caitlin Clappison (@CaitlinClappis1) reported

    @O2 So after waiting nearly a month for a refund, yet again waiting another 5 working days as it was never put through as a refund. No compensation when it’s a breach of basic rights, as a refund should be done within a 2 week period. How do I put a complaint in?

  • mfemigs Migs (@mfemigs) reported

    @CaddyXv @highsy87 @O2 Hardly anyone can. Vodaphone and O2 certainly not. Full 4G signal but no data flow. I complained to O2 and they basically told me it was tough ****

  • highsy87 Martin H (@highsy87) reported

    @CaddyXv @O2 Bet there signal round town doesn’t improve by 8% useless bastards

  • DavidFunwith Fwithdandd (@DavidFunwith) reported

    @O2 Your service is going backwards. I have been trying to set up a simple mobile hotspot and it has been an absolute disaster and a nightmare. Dare I say it, I had a Vodafone system that was more smoother than this and that’s really scrape in the barrel.

  • johnmross1985 john michael ross (@johnmross1985) reported

    I like how @O2 texting my fathers phone asking questions why i rang them yesterday when a told them the passing of him on monday and wanted to cancel his contract

  • lbarcoo84 Lucy Barcoo (@lbarcoo84) reported

    @O2 husbands number has been cloned, people calling him saying they’ve missed a call from him. Credit card also been used fraudulently. Spoke to @actionfrauduk who said call o2 urgently. On phone to rep who cannot grasp what we are asking. Abysmal service. What do we do?
