  • 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!

  • bks67 bridget sparks (@bks67) reported from Hertfordshire, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    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!

  • Greekphotoguy Dimitris A. (@Greekphotoguy) reported from Tottenham, England

    Dear @O2, I've been with you for years. Just upgraded for 3 years. But the fact that I can't take my phone because my European driving license is not acceptable ID is very annoying. It has my photo and name on it. My passport has the same photo! I really don't see the problem.

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • CannyAuldGyruum Abe (@CannyAuldGyruum) reported

    @AppleSupport Hi no that hasn't work unfortunately. He has been to the local @O2 store but they have been unable to help. @O2 anything from you to help...?!

  • CarlosShelu Papii Dee (@CarlosShelu) reported

    @O2 is there a reason why all your customer service number are not connecting

  • Gucci_Hughes 👉🏼 Brad Hughes 👈🏼 (@Gucci_Hughes) reported

    @O2 oh and I've never paid late, my wife's contract is in my name as a joint contract so hers would be affected too if that was the case, just my handset, she has the same one but only difference is mine is an e-sim (by choice) and she has a physical sim

  • GCT1UK Glyn Taylor (@GCT1UK) reported

    @O2 sadly after being a business customer with o2 for over 15yrs I feel its time to switch to alternative network. The reason poor coverage. If you want proof go on your coverage checker for my post code it says excellent. Then stand in my back garden and tell me if it is or not!

  • Gucci_Hughes 👉🏼 Brad Hughes 👈🏼 (@Gucci_Hughes) reported

    @O2 absolutely no signal, not even basic signal for calls and SMS... Been like this now for 2.5hrs and it's not specific to my area as I've travelled from #Southampton to #fareham and my wife's signal is fine. Getting very annoyed QUICKLY!

  • _catlow Martyn Catlow (@_catlow) reported

    @O2 Is that all you folks can offer in terms of support, referral to a resource which is inaccurate, static and does not represent the real world ? I have a service problem and it’s not being addressed, what are O2 going to do about it ?

  • LewisB1983 Lewis Bell (@LewisB1983) reported

    @O2 another company who take money without providing a service!!!

  • CarthySM Simon (@CarthySM) reported

    So upgraded my phone a few months ago with the promise of a £300 gift card with @O2. After repeated emails, phone calls nobody ever responds. Unprofessional, non-existent customer service, see how they like it when I blank their calls and letters for non payment of bill! 🖕

  • theredsnapper marc redford (@theredsnapper) reported

    @O2 Who to and how do we report network issues, 02 Status reports give nothing more than ‘there’s mast issues’ no updates at all even though they’ve been requested! 🤷🏼 #FirstWorldProblems

  • 46karenk karen knight (@46karenk) reported

    @O2 I was promised a reward card of £300 when I upgraded my phone at end of July. Despite a case and complaint being upheld by o2 I still don't have the reward card. How do I escalate this complaint and speak to someone
