  • johndpmc none of your business (@johndpmc) reported from Luton, England

    @O2 words fail me with how shockingly bad you are Your service is appalling, doing a sim swap on my behalf without telling me or having the new sim in my possession!So now no phone or contact to anyone unless in WiFi, wanna hope I have no accidents when I’m outside!! #theworst

  • EmJen81 Matthew J (@EmJen81) reported from Dunstable, England

    @O2 Why, for the past 6 months can I STILL not upgrade my phone online or any of your stores due to your dire lack of stock. I've had this phone for 3 years and it's dying. Yet you never seem to have any stock. Other networks aren't having issues!? Time to switch perhaps.

  • DrHannahLB Hannah Lomax-Browne (@DrHannahLB) reported from Walthamstow, England

    @O2 I don’t know what I’m paying for? Unless I’m somewhere with WiFi I have the worst internet, anywhere I go! I’ve tried all the steps to fix and still terrible internet. Unacceptable!

  • ShanWilson_ Shan Wilson (@ShanWilson_) reported from Hemel Hempstead, England

    @O2 @mtsavor I cannot call 202 or any other number that is supposed to be “o2” as I don’t know who I’m talking to. I’ve been hung up on twice when I’m explaining what’s happened. I need to cancel the iPhone contract or change the address with an actual o2 staff member!

  • ian_slade2 Ian Slade (@ian_slade2) reported from London Colney, England

    @O2 is the data network down? Zero mobile data connectivity all day. Plenty left on the plan

  • paul_a_lewis Paul Lewis (@paul_a_lewis) reported from Barnet, England

    @O2 my wife joined O2 today and ordered a new phone however she provided you with the wrong email address, can you help change it? Thnx

  • 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...

  • JoshBates Josh (@JoshBates) reported from London Colney, England

    @O2 Hi, can you please help me add Spend Cap to my Pay Monthly account? Don’t seem to be able to do this from web site which is a little frustrating to say the least x

  • arigork Ari Gork (@arigork) reported from Barnet, England

    @O2 Any plans on enabling sms over wifi calling? I used to be with @EE and I could call and sms with wifi calling but seems your network only supports calls?

  • Palouisea UnhappyHoopla (@Palouisea) reported from Shenley, England

    @VOXI_UK I have been on a staycation this week I am appalled at how poor your reception is in many parts of South East. Going back to @O2 as sim only!! Very frustrating 😕 missed many important phone calls. Pm me to discuss

  • misswotless1 Miss Wotless (@misswotless1) reported from London Colney, England

    Remind me never to frequent the @O2 store on Oxford Street again - so rude and unhelpful, telling the customer before me not to come back

  • till_the_wheels 𝕵𝖚𝖌𝖘 (@till_the_wheels) reported from London, England

    @O2 @Joegreaney Hi I'd just like to add that this is a problem for everyone on 02 and giffgaff in that area and it's because a mast in hither green has been down for 2 years and these crooks hate you enough to ignore it.

  • carolthomson131 Carol Thomson 🏴󠁧󠁢󠁳󠁣󠁴󠁿 (@carolthomson131) reported

    @Dent29Dent @O2 Good luck with getting through to Customer Service - took me over 2 hours and still didn’t receive help.

  • desdemonaduck Georgie Ancell (@desdemonaduck) reported

    @O2 trying to get help but DMs just say they can't be delivered...

  • dnlltylr Danielle Taylor (@dnlltylr) reported

    @O2 It is NOT an issue with my sim or my phone, please don’t try fob off the issue. O2 coverage is shocking. I’ve been a customer for over a decade and never known anything like it, takes a quick scroll through twitter to see how many people feel the same!!

  • PDooney13 P M.e (@PDooney13) reported

    @O2 Never take selfies ... but I cant even use my phone for calls because you're demanding a payment which you already took from my bank over a week ago. & trying to navigate "Customer Services" impossible. The worst system I've ever encountered, yet from a "Communications" Company.

  • ro65876126 RobbTerr (@ro65876126) reported

    @O2 If you can’t use your phone because the network signal is so bollocking **** in the town and surrounding towns, you’re being conned out of a monthly contract payment. **** O2.

  • SimonKenyon14 Simon Kenyon (@SimonKenyon14) reported

    @O2 good evening your inbox is not working it's just saying I cannot send any messages to it.

  • flawedgod Kee widda E 🔑 (@flawedgod) reported

    💩 and @O2 are the same damn thing

  • ElectricBrahms Bewildebeest (@ElectricBrahms) reported

    @Tankslider @O2 'Oh dear James - please DM us so we can appear to be doing something whilst just ignoring you all over again'. Can never get my head round the fact that there are people who actually think like that. What if a member of their family rang up - would they **** on them as well ?

  • western_emma Ew (@western_emma) reported

    @o2 I’ve had really bad signal for nearly 4 weeks I have been told that a mast is damaged and needs fixing but I can’t contact anyone in a emergency when I’m at home or at work my family are on o2 and we’re paying for a service that’s rubbish.😡

  • FD_BWFC Chris Clifford (@FD_BWFC) reported

    @O2 why do you make it all so difficult ! Just switched to o2 and it’s a becoming a nightmare. No customer service available at all, really disappointed.
