  • 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.

  • 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

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

  • 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

  • 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

  • torgo Daniel Appelquist (@torgo) reported from London Colney, England

    Do you know what? Mobile operators get a lot of scorn, but I have spoken to some really lovely @o2 customer service reps over the last few days who have been very helpful sorting out all my contract and SIM issues. So 👏.

  • 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

  • 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!

  • ReetuKabra Reetu Kabra (@ReetuKabra) reported

    My current hatred for @O2 customer services knows no bounds. Before this site dies - who should I switch to and why?

  • _JuSt__Go_ ClOuSeThUnDeRbOlT (@_JuSt__Go_) reported

    The support team from o2 have been so unhelpful with out issue and even not believing that we recieved a fake phone even after we produced the completely wrong IMEI number, stating that we recieved our iPhone from DPD even though it's completely fake. @O2

  • roshKrish rOsH (@roshKrish) reported

    More and more trouble with @O2 Even after settling everything [ confirmed by O2 in tweet ], still sending an email for huge amount as bill. What a world !

  • cooke_j1 Jen Cooke (@cooke_j1) reported

    @O2 can you help please. Due to a glitch, confirmed by your agents, I was charged for use abroad that I shouldn’t have been. I was promised that this was corrected but you have just taken the full, incorrect, amount. Can you please resolve. This is not acceptable!

  • Kiwiboy41 Ian Wilkinson (@Kiwiboy41) reported

    @O2 priority app still not working now been 10days have tried everything !! Any fixes ??

  • Goulchad adamki (@Goulchad) reported

    Why is there never any phone signal in #stroud @StroudDC @O2

  • join4te Jay (@join4te) reported

    @O2 Day 6 of 365 on trying to get O2 to fix their phone customer service. 1) If you ring and ask for an e-sim for an Apple Watch then good luck with that. Staff seem very untrained. 2) Calls disconnect too much when speaking on 202. 3) The whole IVR system feels dated.

  • CsehZsuzsi Zsuzsanna Cseh (@CsehZsuzsi) reported
