  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • julie_virgo1 julie virgo (@julie_virgo1) reported from Croxley Green, England

    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • Marcus_dd1 Marcus (@Marcus_dd1) reported from Southall, England

    @O2 Hi, my O2 cinema voucher keeps saying that there is a problem adding the voucher. Could you help me to go see James Bond tomorrow please

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • GAdams_Spink Geoff Adams-Spink (@GAdams_Spink) reported from Harrow Weald, England

    So, @O2 is complicit in this rip off but unprepared to do anything to assist a long standing customer.

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • Stevo_j Stevo (@Stevo_j) reported

    @O2 Lol, you think tickets will still be available after 48 minutes, never mind hours?

  • PS5GameBlog Playstation5GamingBlog (@PS5GameBlog) reported

    @O2 Your mobile network is getting like every other network !!!

  • CeiakaPhillips Cei Phillips (@CeiakaPhillips) reported

    @O2 Piss poor @O2 presale lasts 48 hours. Ticketmaster bots only need 48 seconds to hoover up all the tickets and put 300% onto the price. Glad we spent the time yesterday making sure our logins were working.

  • ColinBr75910239 Colin Bright (@ColinBr75910239) reported

    @O2 Poor excuse really! A phone company can’t sort its own technical issues out 🤔😳

  • georgenic1 Nicola Hunt (@georgenic1) reported

    @O2 This explains why my signal is always rubbish when you can’t even sort this out! This was expected 🤔

  • TruleeAwful TA (@TruleeAwful) reported

    @O2 What do you expect us to do just sit here all day!?! Cancel the pre-sale and re-launch at an alternative time. This is Pathetic!

  • lisa_bonny Lisa Boniface (@lisa_bonny) reported

    @O2 can't believe priority is not working!!!

  • DickerDick73 Rich Stephens 🔴⚪️ (@DickerDick73) reported

    @thesockpuppet @O2 Exactly this…..absolute joke of a network and now the one thing they offer worthwhile they mess up!!

  • David47203456 Ilovebrexit 🏴󠁧󠁢󠁥󠁮󠁧󠁿🇺🇦 (@David47203456) reported

    @peterkay_co_uk peter kay Never mind the predicted 02 ticket fiasco I can't even get my free Gregg's coffee because the @o2 app has crashed!!

  • Marc_Burrows Marc Burrows (@Marc_Burrows) reported

    @O2 Or you delay the ticket release until you’ve enabled a new way for users to access tickets via a simplified page. Otherwise you’re just going to be broken for two days.
