  • behu91 Ben (@behu91) reported from Hemel Hempstead, England

    @O2 are breaching trading standards. Have sent me a voucher code but are not allowing it to be redeemed against S21. Apparently due to being a new launch device, however there is nothing in the terms and conditions to suggest this should be an issue.

  • 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

  • lordshaun_ Lord Shaun O’Brien (@lordshaun_) reported from St Albans, England

    @O2 customer services truly are as much use as an ashtray on a motorbike.

  • 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!

  • emmatrainis Emma Trainis (@emmatrainis) reported from Shenley, England

    @O2 I ordered Disney + on 24.12.20 on Priority and have not received an email. Cannot get through on phone or live chat. Please can someone help me

  • a1_nos A1NOS (@a1_nos) reported from Hemel Hempstead, England

    Hey @O2 showing again why you really are market leaders in Customer Service. Big shout out to Lauren. 👌👌👌

  • 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

  • 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

  • JohnDWebb John Webb (@JohnDWebb) reported from London Colney, England

    @Stephen_Neal @O2 It’s the same with @NatWest_Help - their URL is ‘nwolb’ to login and check stuff. Surely these big companies should be leading by example?

    @William251201 @O2 Purple thing kinda looked like a ahem “massager” for a sec, I thought damn o2 know these lockdowns are stressing people. 😳 my brain is tired & pain addled so forgive me. Also how did you get this?? Was with them for 20+ years couldn’t even get a discount on a re contract deal.

  • mrwasteguru the glorified waste guy 🇺🇸ITFC (@mrwasteguru) reported

    @derekjg @O2 If o2 sent me a Celtic scarf and hat I’d cancel my contract 😙

  • NHSSCW_Liam #hellomynameis..Liam RN 🌈 🇪🇺 (@NHSSCW_Liam) reported

    @O2 @MarkEvansO2 @DerekMcManus Please can someone help me resolve a contract issue. I have spoken with customer services 4 times to no effect. They cannot resolve issues until I pass security but I can't as details are not known. The situation is unbelievably frustrating. Please DM.

  • MylaRoshini Roshini Myla (@MylaRoshini) reported

    @O2 - 40 minutes on hold to speak to someone about billing errors. You will not break me!

  • gruffy79 Gary Roberts (@gruffy79) reported

    Hi @O2 I’m trying to get in contact with you about an unlock code for mobile device. As I’ve been cut off already, I can’t log in to my account or use 202 to phone out. Your “live chat” seems to be “dead”. Some help ASAP would be greatly appreciated

  • glitterysparkle Michelle Blundell (@glitterysparkle) reported

    Shocking customer service from @O2 Upgrade ordered Thursday 25/02, wrong item sent out so posted it back. Still haven't received new phone over a week later and no one seems to know what to do from customer service team. Plus no call backs from managers. Please sort this out!
