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

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @under_the_kilt @O2 I wouldve stuck with o2, Good luck with the limited Signal on Voxi 🤞🏻

  • 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!

  • 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?

  • 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.

  • 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.

  • ChristianRad Christian Radnedge (@ChristianRad) reported from London, England

    Something especially egregious about living near The O2, but not having any @O2 signal once again, even though that doesn't make sense. Feels like it should be a massive router for all of South East London...

  • 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? 😲

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

    @O2 your customer service is an absolute joke.

  • 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.

  • Mountie31 Ben Mitch 🇪🇺🏳️‍🌈🇨🇦🏴󠁧󠁢󠁷󠁬󠁳󠁿😎🤪 (@Mountie31) reported from Hounslow, England

    @O2 Phone masts are down at my work and home so not good.

  • 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

  • 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

  • essenby Barrie Thomas (@essenby) reported

    Anyone having issues porting a number to a new @O2 SIM? Put a request in on 27th and heard nothing since, In desperation I phoned them and was told that it would happen today and a text was sent to confirm. But so far no text. Has anyone successfully ported a number recently?

  • Helen_L_S Helen Sutherland (@Helen_L_S) reported

    @O2 Hi, are you having problems porting numbers?

  • Ms_P_Nut Ms P Nut (@Ms_P_Nut) reported

    @o2 Is there an issue with your app? I can’t see my extras.

  • Britnocker Chris Crook (@Britnocker) reported

    @O2 Again I won't be here now for the delivery, looking at the tweets is there an issue with the credit checking

  • walsh73_a AWalsh73 (@walsh73_a) reported

    Fantastic customer service from @O2 twitter team answered my query and sent the documents I needed.. #happycustomer

  • jo81977 Joanne Douglas (@jo81977) reported

    @O2 Customer service is impossible to get hold of. Been cut of twice and webchat is useless, it will not let me start a chat just keeps me going round in circles... Sort it out O2. All I want to do is add WiFi and 4g calling to both my numbers ...

  • Paula_Griffin65 Paula Griffin 🏳️‍⚧️ 💙💖🤍💖💙 (@Paula_Griffin65) reported from Camden Town, England

    @O2 Hi, currently log into 02 Wi-Fi in places like Costa etc but need to change my details as the name it flashes up is incorrect. However it won’t accept either my email or my phone number to change details.. Help please!

  • DrTABailey Tracey Bailey 💙 (@DrTABailey) reported

    @O2 Well, my husband had to hang out the bedroom window to take a call today, so yes there is still an issue. There have been numerous emails, DMs and phone calls. I’m not getting into any more. We will be looking to move our 4 numbers in the new year.

  • DaveRage Andrzej Marczewski 🕹🎸🏳️‍🌈 🇪🇺 (@DaveRage) reported

    Well @O2 have made a terrible first impression so far. Waiting 2 days to see if I will be graced with a mobile contract, but have no way of knowing what's going on without directly contacting them. No proactive communication whatsoever. Really rather wishing I went @EE now.

  • Thommohawk67 Thommo (@Thommohawk67) reported

    @O2 how does one cancel the Amazon subscription through yourself? Thanks
