  • 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?

  • 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

    @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

    @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!

  • CalvinLaurenson Calvin Laurenson (@CalvinLaurenson) reported from London Colney, England

    @O2 is your London 4g network having issues? I have multiple o2 devices that aren't connecting

  • 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

  • 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

  • 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

  • _SonOfTheDesert Kaiser Soothsays (@_SonOfTheDesert) reported

    @O2 Data is unusable where I am (Milan). As stated, I get 3G but can’t use it, all apps say phone is not connected to network. Irony is my wife is with @tescomobile and is getting 5G. Crossed into Switzerland today and got 5G halfway up a mountain but can’t use phone in Milan. 🤷

  • PokerDaz9 Daren Taylor (@PokerDaz9) reported from Radipole, England

    The @O2 network has to be the worst ever. Even with a strong 4G signal, you still can’t get any data use!!! Certainly over subscribed. #notfitforpurpose #OFCOM

  • Itslaurajane89 Laura Jane Minto (@Itslaurajane89) reported

    @O2 2/2 from the o2 shop in Durham, he couldn't have been more helpful and did go over and above to help me this morning!

  • michelle_moomin Michelle Annie (@michelle_moomin) reported

    @O2 Absolutely shocking service at your Cribbs Causeway branch. So much so, a lady followed me from the store to say she had the same issues with them.

  • 6thGrom Grom McGromface The 6th (@6thGrom) reported

    @O2 Apologies. With the fold you don’t offer loss or theft. Only accidental damage

  • JamRuler89 James (@JamRuler89) reported

    @O2 Barely getting 3G while my wife is getting 5G on another network. Why can’t O2 improve in Lanarkshire?

  • tony_sutton Tony Sutton (@tony_sutton) reported

    Paid for 24 hours of Data SIM with @O2 which was activated straight away and clock counting down. Never worked, even after many device reboots and trying various O2 profiles. Tweeted & DM'ed @O2 - no reply. 24 hours is expiring soon. Waste of money. :/

  • Itslaurajane89 Laura Jane Minto (@Itslaurajane89) reported

    @O2 It's OK, I've been into my local o2 store this morning. Turns out @SamsungUK just lies to their customers and you don't take a contract out with o2 tiu just their network, turns out samsung use a third party network provider! However do want to give a shout out to Jack from the

  • ajameson1008 Amy Jameson (@ajameson1008) reported

    @kellyja90235455 @O2 Me too! Two contracts taken out fraudulently and can’t speak to customer services unless I pay the fraudulent account! Seems to have happened to lots. I’ve never been an o2 customer! So stressful

    @O2 my voucher for a sausage roll said it had been used but I never used it yet
