    @O2 #02priority can't seem to get a code for hairspray.. Can you help? 😲

  • 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!

  • ashley_leggett Ashley Leggett (@ashley_leggett) reported from Hounslow, England

    @O2 your signal in Hammersmith is a joke. London in 2021 and can’t even make a phone call.

  • 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 👌🏻

  • natejrogers Nate Rogers (@natejrogers) reported from Wokingham, England

    So my @O2 contract has now gone back to its normal price (which is double). Does that mean I’m now going to get double the service? I bloody hope so, cos it’s pretty sucky at the moment.

  • 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

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

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

  • 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.

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

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

  • 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!

  • DebsHaden Debbie Haden (@DebsHaden) reported from Slough, England

    @O2 I need somebody from your customer services team to contact me straight away! Your website is taking me round in circles and not helping. I should have had my contract cancelled and it hasn’t happened. So still paying out for it. Not happy at the moment.

  • 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

    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.

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

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

    @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

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

  • 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

    @O2 Why did it run out? It never ran out since March 2020.

  • thatgirlthere14 ...-- (@thatgirlthere14) reported

    @O2 you absolute joke of a network

  • dancoops1 Dan Cooper (@dancoops1) reported

    @TuftyMUFC @O2 I wish they’d cut your signal your a boring fella

  • staceyhillx Staceyhillx (@staceyhillx) reported

    @O2 I just can't get far with my data..it just doesn't work 80 percent of the time

  • JessiicaLouiise x 𝐉𝐄𝐒𝐒𝐈𝐂𝐀 x (@JessiicaLouiise) reported

    why is my signal and internet so rubbish lately? one bar of signal, nothing ever loads off the wifi.. and my calls are constantly dropping. @O2 😑

  • nicksagar Nick Sagar (@nicksagar) reported

    Be careful when porting a number to @O2 - the port may activate before your sim arrives leaving you with no service with either provider. Not a great start @O2 !!!

  • PeterClaydon Peter Claydon (@PeterClaydon) reported

    @giffgaff Bristol Temple Meads and Paddington are fine. It's Reading and Bath Spa that are the worst, with Swindon and Didcot Parkway not very good. It's not your fault. It's @O2 (or whoever does the network in those stations).

  • GraceAxHa Grace Redmond (@GraceAxHa) reported

    @O2 Having issues tracking my order. Attempted delivery on Monday but was at work. Haven't tried again since DPD Parcel No. 1550 1623 937 058 T

  • ziaabbasi zia abbasi (@ziaabbasi) reported

    @O2 you are the worst network and customer service in UK by any means.

  • smots_gtfo brian (@smots_gtfo) reported

    @ThisIsCMBarnes @O2InstituteBham @O2 I don't really care what they've done tbh, as long as the music sounds good I'd be fine seeing anyone. If it was that bad they'd be in prison.
