    @O2 sort out your customer services ! Waited ages and because the operator didn’t like me saying how ridiculous the service was he cut me off!!! #disgusted

  • nickysinclair Nicky Sinclair PGA (@nickysinclair) reported from Windsor, England

    @O2 why are the iPhone 12 deals better for a new customer than an existing long time o2 user? #absurd

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    If I was a shareholder in @O2 rather than a loyal customer today would be the day I sold.

  • sarahspoon Sarah (@sarahspoon) reported from London, England

    @JamesIMcKay @O2 Oh….never heard of it. Ta

  • MrsScreech Jess (@MrsScreech) reported from Hillingdon, England

    @O2 please sort out the broken mast in Yiewsley. Only having the capability to make WiFi calls from home for weeks on end is becoming frustrating!

  • SarahScogley Sarah cogley (@SarahScogley) reported from Bracknell, England

    @O2 your customer service is an absolute joke.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

    @O2 I rang 202 and they said there was nothing they could do for me, just to change my password Will text that number now, thanks for your help 👌🏻

  • musical_IH Iain Hunter (@musical_IH) reported from Spelthorne District, England

    @Br1tt3n @AppleSupport @O2 I’d imagine it’s more a network issue. My iPhone 12 Pro is gorgeous and hasn’t put a foot wrong

  • amylouisestone Amy Stone (@amylouisestone) reported from London, England

    @O2 I have also been doing this too. If this problem persists, then what?

  • aamer74 aamer habib (@aamer74) reported from Maidenhead, England

    @O2 @England My ba p2 priority codes for the cinema are not working

  • GeorgeGower_ George Gower (@GeorgeGower_) reported from Blackwater, England

    @O2 unable to log into my o2 online to upgrade. Password etc is correct, but it’s not loading the page on numerous devices. Is there any known issues?

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    @O2 Tried everything. (Apart from trying SIM in another phone). Previously if ever ‘SIM not working’ flashed up all I had to do was switch phone on/off. Not this time. Help!

  • T_Morris_Wealth Tim Morris (@T_Morris_Wealth) reported from London, England

    @emmahaslett @O2 Very good point. These things do tend to penalise the more vulnerable/worse off. I work with clients in the former category to help them become more tech savvy and keeping track of their finances. The latter don’t receive much support

  • carboncoach Dave Hampton 🌍 (@carboncoach) reported from Marlow Bottom, England

    My SIM only service with @O2 has packed up inexplicably today; and O2 slow to respond. Anyway I am without phone. So please DM if you need me.

  • MissusWebb Sarah 🧡 (@MissusWebb) reported from Burnham, England

  • Kierbro Kieran Brown #FRSA 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇪🇺🏳️‍🌈 (@Kierbro) reported from London, England

    @O2 I will! If you could sort out anything at all, that would be amazing...! I’ve been a loyal customer for more than 20 years so it would be much appreciated..!

    @O2 I have never had such **** signal since with you. How ******** can you not get signal In the middle of bloody London. Pathetic.

  • yorkshireman67 Tim Gisburn (@yorkshireman67) reported

    @O2 Absolute **** show, how is this still not fixed?

  • BabyBoomer1960 Karen loves wildlife 🐘🦧🦏 (@BabyBoomer1960) reported

    @watsee @O2 Sorry for having a go but theres always problems when someone high profile announces a tour, so why @O2 are using that overused word (since covid) ‘unprecedented’ I’ve no idea. They knew there’d be issues but has is usual it’s not their fault.

  • stumak83 Kevin NOT Perry (@stumak83) reported

    @O2 Been sent 4 codes now throughout the day and still cannot login for these @peterkay_co_uk tickets

  • chrisma5on chris mason (@chrisma5on) reported

    You’d assume if @O2 priority had a decent amount of presale tickets and their site/app has been down all day they’d still have their pre-sale allocation to sell, but more people are now saying the pre-sales sold out, it’s an absolute shambles #O2Priority #peterkay

  • LawTRICIA Tricia 💙 (@LawTRICIA) reported

    @virginmedia the @O2 priority tickets site down all day 😡

  • maddiex315 🌷 (@maddiex315) reported

    @O2 can’t get into my priority account, you send me the security warning text but not the code to get in, sort it out and help me @TheO2 @O2

  • saul03857335 saul (@saul03857335) reported
