  • 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.

  • 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. 👌👌👌

  • 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.

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

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

  • 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

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

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

  • 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

  • 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

  • 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?

  • 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.

  • 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

  • happyinabook Amanda went out for the first time in ages (@happyinabook) reported

    @O2 @virginmedia We've used Virgin in the past and frankly they were so awful this puts me off staying with O2 in the future. 🤔

  • MattyBx9427 MattyB (@MattyBx9427) reported

    @SkyHelpTeam @O2 What IS THIS Gone Into Portsmouth For The Day 3G 3BloodyG In Portsmouth This Is Rubbish @O2 Don’t Even Make Me Get Started About Signal At Home Speeds Here 0.32 MBPS Down

  • Philsnr Phil🇬🇧🇮🇱🏴󠁧󠁢󠁥󠁮󠁧󠁿🏴󠁧󠁢󠁷󠁬󠁳󠁿🏴󠁧󠁢 (@Philsnr) reported

    @TheRoonMeister @virginmedia @O2 I've been a loyal customer for almost 20 years, I just get treated like a cash cow

  • Veronica_Strain Veronica Strain (@Veronica_Strain) reported

    @BLFCxx @Chriss_m @O2 I stayed with Virgin long enough to wriggle out of the contract with barely an ounce of sanity left. TV - never had the correct channels, phone - connected to someone elses number of 3 mths. Genuinely horrible company.

  • Veronica_Strain Veronica Strain (@Veronica_Strain) reported

    @david_harman_uk @O2 @Ofcom Totally. Virgin is horrible company generally and not one I would ever sign up to.

  • ArtetaOutt Arteta Out (@ArtetaOutt) reported

    @O2 @virginmedia I'll be leaving o2 the second my contract is up. I want nothing to do with that god awful company

  • James97370332 James (@James97370332) reported

    @O2 @virginmedia This is awful news. How long until my pay as you go tariff is take away? It's already no longer available to new customers. I've been on this network since it was called Cellnet, and have happily avoided Virgin in that time.

  • mike_johnson Mike Johnson (@mike_johnson) reported

    @virginmedia @O2 I'm bothered by this - I left O2 when they refused to give me a working phone and left me uncontactable. I'd have been able to see my grandmother before she died if they'd provided any kind of proper service.

  • Tourayjax Jackie Touray (@Tourayjax) reported

    @ElaineW30559995 @virginmedia @O2 I’ve been with virgin for 8 years and never had an issue where I think they are great

  • Ghoul_of_London ⚠️Skeleton O'Rourke⚠️ (@Ghoul_of_London) reported

    @O2 @virginmedia What a pity, joining up with such an awful uber-profiteering company with appalling customer service. I will be reviewing my options pretty soon.
