    @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

  • akasha303 Greg Meeres (@akasha303) reported from Twyford, England

    @O2 Your web chat support team advised I ‘needed’ to call Equifax, rather than Experian, even when I queried (as I have an Experian account). Might want to check the process playbooks! (Issue is now resolved through a work around).

  • gonnella Pete (@gonnella) reported from Woodley, England

    @O2 frustrating deal with you guys, 6 months of poor service. Now dealing with your networks team, you quite obviously have a coverage issue in my area. Please just let me leave my sim only contract early thanks.

  • PGcomms Peter Gordon (@PGcomms) reported from Guildford, England

    @O2 hi there - my 3G/4G data facility on the phone hasn’t worked for some hours. Mobile phone signal ok. Is there a data prob?

  • 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

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

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

  • Jenzy84 Jenna Christie (@Jenzy84) reported from Wokingham, England

    @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

  • stevejonathan80 Steve (@stevejonathan80) reported from London, England

    Poor network in Se6 @O2

  • ollieeden Ollie Eden (@ollieeden) reported from Farnham, England

    @O2 I’ve been a customer for nearly 20 years, but I will be more than prepared to switch if you fund / pay for advertising on #GBNews #DontFundGBNews

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

    Hello @O2 I am back 🙌🏻 after a few years with no signal, awful service I have come back with my tail between my legs 🙈 #ohtohavesignal 🥳🥳🥳

    @O2 your customer service is an absolute joke.

  • 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!

  • 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..!

  • ShaneyFirkins96 Shaney (@ShaneyFirkins96) reported from London, England

    @O2 Is the network down?

  • FPLJazz01 FPL Jazz (@FPLJazz01) reported

    @Irons_FPL @AnthonyUsher @O2 It’s been 7 days for me! Still no luck and cut off from previous provider. Can’t so much as make a call or receive a call. I’ve dropped off the planet. Was told it’s possible I’ll lose my no for good! 😡 Temp number doesn’t work either, no network. Absolute joke!
