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

  • 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.

  • 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

  • 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

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from London Colney, England

    @O2 full 4G signal in Chelsea and can’t even load a PDF attachment or Instagram post. Absolute shambles. Same over in white city. Same in London Bridge. Got better service last week 2000M up a mountain in Austria

  • 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.

    @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

  • 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.

  • philter66 Phil Turner (@philter66) reported from Hatfield, England

    @O2 simply dreadful customer experience tonight -felt really let down

  • 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!

  • HilaryRWriter Hilary Robertson (@HilaryRWriter) reported from Hitchin, England

    @O2 Yes. I’m trying to cancel my mobile broadband and cannot do it on myO2. The ‘help’ keeps sending me round in circles

    @lovesid1 @O2 Same situation and o2 and bmd don’t give a ****.they are both in on it.

  • deepestenigma tracy davis (@deepestenigma) reported

    @O2 It usually just says sold out though. Plus it’s only a minute past 2 when I took the pic, I was on before 2 waiting. I know they go quick but when I remember I usually manage to get one for both accounts. Just hope there isn’t a problem with accounts.

  • LucyCoo08479560 Lucy Cooke (@LucyCoo08479560) reported

    @O2 hi, I’ve had a ‘come back to Disney+’ text from you offering me disney+ for £5.99 a month but when I click through to priority there is a message saying ‘we can’t show you this extra right now’. Please help!

  • JamesGordelier James Gordelier (@JamesGordelier) reported

    . @MPD_Online my friend ordered an iPhone 14 pro 2 weeks ago from @o2 and hers is arriving tomorrow! How come I’ve waited 10 weeks and still nothing? How do I cancel might order?!

  • _ColinGriffiths CG (@_ColinGriffiths) reported

    @O2 Shocking phone reception in Bridgnorth. Be nice to get it sorted before 2023. "Looks like a nearby phone mast isn’t working as it should, sorry. Our engineers are likely to be on the case already, and your service might come and go until we fix it"

  • chris82713267 chris (@chris82713267) reported

    @O2 hello I have tried to get tickets for odeon and it just says there is a technical problem I was on at 2pm can you please send me a code

  • swiftieprateeek “AHH you are prateek!” ❤️✨ (@swiftieprateeek) reported

    @O2 I have a prepaid sim and I keep getting no signal. I think it got deactivated? Can you please activate it? Thanks!

    @O2 & @madebygoogle when will the O2 UK network get #PixelWatch LTE capability? Seems like someone is on the naughty list, must try harder in 2023? #TeamPixel #PixelWatch

  • SueDown51169163 Sue Downey (@SueDown51169163) reported

    @O2 can I have my login number please I can't access my account you sent it but I lost the text

  • AureliusMari Aurelius (@AureliusMari) reported

    @O2 I will be reporting you for your lack of communication and service you didn’t provide. For months, the mast in my area has been down, I have informed you several times but you kept telling me an engineer is on the case but nothing has been fixed yet. @Ofcom
