  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • RaviDheer Ravi Dheer (@RaviDheer) reported from London Colney, England

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

  • EdwardsHimself Edwardshimself (@EdwardsHimself) reported

    @O2 I had call today from a random number in Leeds, confirming to me that you as my network are selling numbers to cold callers. I’m sure there is a policy/law under GDPR that forbids you to sell my information. Happy to give you a call to discuss cancellation of my contract.

  • jm1967uk Justin Moore (@jm1967uk) reported

    @O2 Hello, I'm in Bowness-on-Windermere. Your coverage here is dire. I switched on airplane mode, restarted my phone etc. Can I have part of my monthly charge back please? Your service here is useless.

  • hilary1951 Hilary (@hilary1951) reported

    @O2 I am unable to phone out please can you help me

  • bryan_hulme Bryan hulme (@bryan_hulme) reported

    @O2 sick of having no signal! My phones saying ive got 4g but nothing loads 🙄🙄

  • hevluvsbags Heather Axton 🐍 (@hevluvsbags) reported

    @O2 once again my signal disappears or is very weak sorry 02 I might be needing to look at a different network this keeps happening

  • giinagii GiinaGii 🐱🎃 (@giinagii) reported

    @O2 Having an issue with my Disney+ extra, can't contact you as it just says 'all agents are busy not even a queue system. Can someone help with this please, we're still being charged and we're supposed to get 6 months free. Thanks.

  • OooPooLooMooZoo Seonaid MacKay (@OooPooLooMooZoo) reported

    @O2 have been asking for a week for simple answer to question about leaving o2 and termination fees. Now referring o2 to ombudsman as your Twitter customer service is dreadful. You’ve take days to reply and been no help at all, your lack of advice may have cost me £400.

  • NicholasDan1el Nick Ford (@NicholasDan1el) reported

    @stevend66768143 @O2 Two weeks and still awaiting stock on the O2 site for me…I’m also upgrading to replace a broken phone so until I can get it I am literally without a phone. They seemed clueless on when they’ll actually arrive too…😡

  • jamiejeonex Jeonex (@jamiejeonex) reported

    @O2 stupid ******* child why would you eat pizza like that you dumb ****

  • rarrah_crypto The Crypto Babe (@rarrah_crypto) reported

    .@o2 also - your Disney plus package is a rip off SCAM. You didn’t make it clear it was a one year contract that you can’t cancel!!!! Even Disney allows you to cancel. Didn’t know o2 were thieves.
