    @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

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

  • 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

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • sparkloaf26 mark cording (@sparkloaf26) reported from Barnet, England

  • AlanGreene73 Alan Greene (@AlanGreene73) reported from London, England

    @StudiniJones @timlukejones @O2 Yep I thought the 13.3.2 update had fixed it but I’ve lost signal again this morning. Had to reboot my phone. I’m on latest update. Pissing me off now. People can’t call or message me until I’ve realised and turned phone off&on

  • 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.

  • AshleyLlewellyn Ashley (@AshleyLlewellyn) reported from Barnet, England

    I have before, but I keep getting told there is no issue with the mast. Or use WiFi, or get a new sim. I just want to be able to use my phone, thinking about ditching you guys and going to @O2 might get a signal and a betting offer on s phone.

  • TRFC_Tom Thomas-Lee (@TRFC_Tom) reported from London, England

    @craigglawson @inoobkilervip @O2 @BBCWatchdog @monzo No they said they couldnt see any issues, hence they getting specialist team to look into it. Its been happening for 3 days.

  • missSarah1980 Sarah Jane O'Grady (@missSarah1980) reported

    @O2 I have managed to call and pay over the phone, do you have any idea when my service will be unrestricted? Thank you

  • kathryn_felton Kathryn (@kathryn_felton) reported

    @O2 Still no joy. This was supposed to be available within 24hrs yet 5 days later and still not able to activate. I’d find it more believable that the service was busy if I didn’t have to be up for work at 3am, the link still wasn’t working at that time of day

  • GrantShipway Grant Shipway (@GrantShipway) reported

    @O2 Would help if you responded to complaints so I can escalate to #ofcom

  • rexthomc Thomas Charlesworth (@rexthomc) reported

    @VMO2News @O2 @virginmedia Broadband/Fibre and TV has been down in CT9 2NA for the past 2 days. Service status site says technicians are "fixing it". I've walked along the roads in the area for the past 2 days and haven't seen any technicians working on anything lol. Our Christmas is RUINED.

  • TutthillRichard Richard TUTTHILL (@TutthillRichard) reported

    @O2 I have been all the time I've been with 02. No signal at home, no signal 2 miles away at work. My contract not fit for purpose.

  • CharlieWithey6 Charlie Withey (@CharlieWithey6) reported

    @ComeOnFella_ @O2 Been awful! Been on hold for hours the whole of December. And nothing no further forward except someone will call me back. But never do. Good luck.

  • KarenMMM2000 Karen M. (@KarenMMM2000) reported

    @O2 what an absolute nightmare calling your customer service today…after about 10 calls and at least 5 dropped off by yours employees, still no one could help me ! Congratulations O2 !!!

  • ParkyTri David (@ParkyTri) reported

    @O2 I’m still waiting for confirmation on our Disney+ trial. It’s sitting in my account but I get an error page when I click on it so can set it up! Can you please help.

  • LittleMissAlexC Alex Cameron (@LittleMissAlexC) reported

    @O2 @Allan96673636 Keeping refreshing and no update since Monday isn’t good enough. All well and good to give an offer, but don’t say the site is broken, there’s a missing link that is simple. Please update us. People want it for Christmas

  • WrightDpw David Wright (@WrightDpw) reported

    @kojecat @O2 O2 clearly underestimated the volume of customers who would take up the offer. I have spoken with their customer services on 2 occasions this week and have been told different things each time. This is a technical issue which should have been sorted.
