    @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

    @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!

  • 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.

  • 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 👌🏻

  • 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

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

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

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

    @O2 your customer service is an absolute joke.

  • 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

  • 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.

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

  • 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.

  • 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?

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

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

  • 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

  • Andrew_Cdf AndrewRMitchell (@Andrew_Cdf) reported

    @O2 Not much help ta. A “yes we have an issue in you area at the moment etc” would have been more helpful. I found an o2 system checker last night that said there were issues.

  • Natalie80436441 Natalie (@Natalie80436441) reported

    @O2 Hi O2 just to make matters worse I sent a formal complaint 3 weeks ago and haven’t heard anything back.

  • farrenciaran Ciarán (@farrenciaran) reported from Blaydon-on-Tyne, England

    Hey @O2! 👋👋👋 You are really starting to make me angry. Why is my internet connection very slow, even when on 4G. I cannot deal withe pausing videos, apps and webpages not loading. Sort it out!

  • stevicoos Ojeaburu Stephen (@stevicoos) reported

    @O2 I must not be debited wrongly or I pick up this issue legally

  • peter33266430 peter (@peter33266430) reported

    @O2 this has to be the worst phone mobile provider, I must have been a idiot to come to these idiots , the reception is crap , so o2 have disconnected my devices for 4 hours , it’s been 8 hours know , they have forgotten it should have only be for 4hours

  • stevicoos Ojeaburu Stephen (@stevicoos) reported

    @O2 Good afternoon O2. Am Stephen Ojeaburu with phone number 07423124389 which I was force to use your sim due to Virgin media that I bought. I have 2 issue, first is with the contract, we agreed to keep my number and also to continue paying 10£ that I was paying

  • goonerlgh Lawrence ****** 🇺🇦 (@goonerlgh) reported

    @O2 why do you block numbers using the 18001 prefix that is for the RelayUK deaf persons call service??? Why would you do that???

  • stevicoos Ojeaburu Stephen (@stevicoos) reported

    @O2 Your DM is not working. I will take this more serious. All your customers service agent are not professional I have all my calls recorded with them and their names mentioned by each person.

  • queenie_mag Queenie Mag (@queenie_mag) reported

    @O2 Just had the most amazing customer service from Saffora on your helpline today. Thank you 🙏

  • sdb Steve Bentley (@sdb) reported

    @o2 do I really need an email, SMS and app push alert telling me that my bill - which is paid by Direct Debit and identical to every other month - is ready? A heads up if it's unusually high makes sense, but 3 separate notifications about a non issue?
