    @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

  • 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!

  • 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?

  • 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..!

  • 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.

  • 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

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

    @O2 your customer service is an absolute joke.

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

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

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

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

    Poor network in Se6 @O2

  • 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.

  • 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!

  • 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

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

    Got to Love when your on @VOXI_UK using @VodafoneUK Network but your Phone keeps switching between a @O2 Mast and struggling to connect to a Vodafone Mast and both ain't recieving interent 5G,4G or 3G. Myself on Voxi and Nan on Vodafone ain't recieved interent for the past 2 hrs

  • 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.

  • 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

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

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

  • steveokeeffe62 Steve O'Keeffe (@steveokeeffe62) reported

    @virginmedia I bore with you until it was all sold out. You and @o2 have a very annoyed (soon to be) ex customer on their hands. I’m sure I’m not alone.

  • DjCelia Gary Celia (@DjCelia) reported

    @O2 worst network in the uk. Terrible signal and even worse customer service

  • mh_07_jch Cher Hendley (@mh_07_jch) reported

    @O2 Really? And just how exactly has your allocation of tickets sold out when none of your genuine O2 priority customers could log into the app / website all day? This is an absolute joke @o2 @peterkay_co_uk Feels so great to be an O2 customer with priority access - NOT 🤬

  • FlakeyFernandes FlakeyFernandes (@FlakeyFernandes) reported

    @O2 think it’s safe to say you’ve lost a lot of customers today as you’ve not been prepared. My contract ends in December and I can’t wait to move on to EE it a competitor you offer the worst service I’ve come across. No signal anywhere and the “perks” don’t even work. #fail #o2

  • ajb1975 Angela Beardsmore (@ajb1975) reported

    @O2 app still down so no Greggs treat today. Sad times 😭

  • mic69449413 mic (@mic69449413) reported

    @O2 @O2 not even angry that had no chance of getting Peter Kay tickets but to have the app crashed so can't get free drinks Thurs night and free Gregg's Fri breakfast is just beyond bad

  • jemmzyy Jemma 🦋 (@jemmzyy) reported

    @O2 How ******** is that even possible when no one could even get on to buy any ???

  • Forzie67 Shaun Foers (@Forzie67) reported

    @PaulineW35 @O2 I've been trying to log onto the app since last night to no avail because its been down. I'd like to know how people have been able to get the priority tickets?? 🤔. Pointless benefit for Virgin media subscribers #o2priorityshambles #virginmedia

  • xXMAUI7Xx xXMAUI7Xx (@xXMAUI7Xx) reported

    @O2 Hahaha hahaha absolute joke tbh I wasn't expecting much from youse your network is actually awful if I'm not connected to my WiFi at home my phone is useless worst network by a long shot

  • George2Charlie Charliegeorge (@George2Charlie) reported

    @O2 @virginmedia any idea how many non O2 and Virgin customers got tickets yesterday.Only people I see getting tickets got them via a direct link folk posted on twitter. Initially I was annoyed I never got on priority App yesterday but it’s worse that folk got them without app
