  • 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.

  • 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.

  • 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

  • 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!

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 I have been trying to talk someone ... please can someone get back to me! I need urgent help.

  • hiaw61 Robert Frame (@hiaw61) reported from Hatfield, England

    @O2 just to say that I have received a replacement phone which is a positive, however I hope they take this example of my frustration with their Customer Service in to consideration and keep their valued customer updated

  • 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.

  • 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

  • JanGoodeve Cllr Jan Goodeve (@JanGoodeve) reported from Hertfordshire, England

    @traceylsteve @O2 @GreggsOfficial I had the same issue in the #Hertford store, the app just said to try again later so ended up paying.

  • 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?

  • GoonerKJP Kaz 💋 (@GoonerKJP) reported from Stevenage District, England

    @O2 when I upgrade with a different network next week do I cancel my direct debit with you? Or do you do it ? @Barclays

  • 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

  • lovepbx Pauline (@lovepbx) reported from Waltham Abbey, England

    @O2 can someone from customer services contact me ... I need urgent help ... Thanks

    @O2 hello the last month I’ve been having issues sending sms messages from home. They just keep failing. Coverage map says full 4g calling but we don’t even get that outside let alone inside and now I can’t even send an sms. The online form to report issues keeps coming up error.

  • tmw1000 Tina Walsh (@tmw1000) reported

    @O2 It's not working again.

  • TootinandBeepin Adam Harvey 💙 (@TootinandBeepin) reported

    @helloimnicholas @O2 @EE I need to switch provider though as Three don’t currently support Watch sims. So it works fine when it’s near my phone but wouldn’t away from it.

  • Darrenm_94 darren (@Darrenm_94) reported

    @O2 Still not received the email I was promised after speaking to someone on the 16/03/2022 about my complaint as I was unable to speak on the phone at the time. I have given it till almost 5pm Monday like you said to do and the number they called me on I can't call back on to chase

  • roxxatw Roxie Fog 🤘 (@roxxatw) reported

    @O2 hi got a flip3 & keeps saying network unavailable or when sending txts it defaults to mms. Is there any network settings i can try to see if its the phone thats faulty?? The sim card is fine in other phones

  • wayne386 Wayne R[]berts 👌 (@wayne386) reported

    @O2 I’ve been a o2 customer a few times over the years and always found the signal & data rates -vs- the other mobile network poor.

  • sibbo1980 justin sibbons (@sibbo1980) reported

    @O2 I've sent you guys an DM, could you have a look and help please. Your customer service is nortirosly slow in responding to emails and this seems to be the only function to talk.

  • lisa_burford Lisa Burford (@lisa_burford) reported

    @O2 hi can someone help me with my mums phone she has no service ?

  • AdamRutherford Dr Adam Rutherford (@AdamRutherford) reported

    @O2 They hung up on the call while I was on hold. I called back, spoke to someone different. They hung up while I was on hold again. No call back. Breathtakingly bad customer service.

    @AdamRutherford @O2 I left @O2 because of customer service.
