    @Ali_Malik @O2 @Ofcom @MarkEvansO2 I’ll give them a #Valentine chance - never had issues before but now only on crucial days they go down. #

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 remember few months back when @o2 was down for nearly 2 days.. after that it’s service is going down everyday.. sometime when you are travelling and passing from certain areas O2 service will simply shift to 3G form 4g and sometime it will be No Serive at all 1/2

  • ItsMeEllisxD Ellis Brown (@ItsMeEllisxD) reported from London Colney, England

    @O2 Well it’s every time I leave Leicester. Or go to a new city.. even when I have 4 bars it’s either really slow or won’t load at all!

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 #o2guru said they are doing a network investigation for me. It makes no sense to use 1GB of data in 53 minutes whilst at the theatre. I’d have to be live streaming for that to happen! #o2 @TheO2 #1gbdata #goinggone

  • johnsheppard71 John Sheppard (@johnsheppard71) reported from Chalfont Saint Peter, England

    @O2 I am an o2 customer for over 20 years ,I am not happy that I am due for an update and you cannot compete with other companies. Where is the loyalty to your customers .

  • Craigcanfield Craig Canfield (@Craigcanfield) reported from Welwyn Garden City, England

    @O2 contract finished.. put on a rolling month deal.. nothing will change they said... 2 days now with no phone signal.. "sim provisioned"! Customer svc say it'll work soon. Gggrrr

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    every single day your service going down ,moved to O2 from 3 , paying more getting less as compare to 3 but your service is kind of same , most of the places it just disappears, call failed, hardly one bar most of the time and no service at certain places.. v disappointing @O2

  • Macgregor11 Glenn macgregor (@Macgregor11) reported from Harrow Weald, England

    @O2 What's the situation for those of us that have recently taken a contract out with you with you supplying a Huawei device. Increasingly potentially losing all support for the phone now

  • Ali_Malik Ali Malik (@Ali_Malik) reported from London, England

    The ordeal continues. @O2 and it’s #CustomerService is very good at taking notes but appalling at resolving complaints / closing issues. Generated an incorrect / inflated bill despite multiple assurances otherwise! Now running pillar to post, no resolution in sight @MarkEvansO2

  • juliet_gough juliet gough (@juliet_gough) reported from London Colney, England

    @O2 I tried. I think you guys list connection. The guru went to check and never came back!!! 🙈😩 @o2 #o2guru

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 i have few screen shots of different areas when it’s service just disappears, call failed and only 1 bar, will share screen shots with @O2 3/3

  • Elissa524 Elissa Da Costa (@Elissa524) reported from St Albans, England

    @O2 Not sure what happened but all ok now thanks. Very good service to get me reconnected quickly

  • LydiaElenaxo Λυδια-Έλενα (@LydiaElenaxo) reported from Tottenham, England

    After 11 years with @O2 they are really trying my patience today.. I’ve been a loyal customer and honestly upgrading has been horrendous with you.. I think @EE might be my new home from today

  • The_Lady_Jade_X Mrs Lady Jade ❤ (@The_Lady_Jade_X) reported from London, England

    Mother in law will deffo b leavin @O2 when her contracts up. She’s been abroad loads n never had issues. Goes Jamaica with new iPhone no issues. Goes to Europe with iPhone and no network. Apparently she needed to call them before n get a bolt. Load of rubbish! CS no help either!

  • DimitthriV Dimitthri Vithanage (@DimitthriV) reported from London Colney, England

    @O2 what is going on! 😭😭 Even when I have signal it's so slow!

  • jmcomms Jonathan Morris 📱📸 (@jmcomms) reported from London Colney, England

    @VModifiedMind @benwood @EE @VodafoneUK @ThreeUK @O2 Albeit using half rate codec for voice. Sounded pretty awful.

  • bks67 bridget sparks (@bks67) reported from Hertfordshire, England

    @O2 I do have the app, I think I will phone the customer service team and ask them,

  • usmanyounas0011 Usman Younas (@usmanyounas0011) reported from Walthamstow, England

    @HowardGriffiths @O2 and if you are on call your call will be dropped(call failed)then it will take sometime fr service to start working again.. 2ndly most of the places getting only 1bar and very slow data browsing.. 3rdly when it connects to 3G it’s same like No Service it goes sooooooo slow 2/2

  • CorinaWieland Corina Wieland (@CorinaWieland) reported from London, England

    @VictoriaGoodyer @O2 Exactly what I will do! I was hoping the more expensive monthly rate (to other providers) is justifid by the costumer service. How wrong was I! Fed up with the poor service, signal cover (in London!), weekends without data and now this.

  • Steve_Edwards77 Steve Edwards (@Steve_Edwards77) reported from Hertfordshire, England

    @westspice @O2 Awful service for me today!

  • ChrisGBurns Chris Burns (@ChrisGBurns) reported

    @BorisJohnson @virginmedia @O2 You campaigned to allow the others to reintroduce roaming fees. Idiot.

  • Fortitudednb Adam Fortitude (@Fortitudednb) reported

    @tomhfh @virginmedia @O2 I bet they won't as they're both ****.

  • travelmad75 myopinion (@travelmad75) reported

    @NadineDorries @virginmedia @O2 Such rubbish. The EU cant legislate on what is clearly a company decision once you are out of the club. You guys can address the issue after you sort out the promised cheaper bills, food, VAT. Pretty sure though you wont do anything.

  • pol88888 🤣🤣🤣🤣 (@pol88888) reported

    @BorisJohnson @virginmedia @O2 I mean is that meant to be good news !! Worst PM ever !!

  • laurainemaria Lauraine (@laurainemaria) reported

    @BorisJohnson @virginmedia @O2 Shame Virgin and O2 have such a poor reputation for coverage and customer services though. I would rather stay with EE , a reliable network and great customer service

  • KateL_30 Kate (@KateL_30) reported

    @TheatreTokens @O2 Hello. I managed to claim a code from O2 successfully and took about 20mins trying the process the order on your site and then once code entered said promotion fully claimed even though I have a valid code. My husband experienced exactly the same issue aswell.

  • TrickyTreesDave ⭐️🌳⭐️ (@TrickyTreesDave) reported

    @BorisJohnson @virginmedia @O2 Trouble is you struggle to even get a signal with #O2 when you're in the #UK they're shocking, ive had no joy with there customer service either, never will i take another contract out with them what a complete waste of a contract....

  • JFRitte Jim FR (@JFRitte) reported

    @BorisJohnson @virginmedia @O2 NONE OF THIS WAS DOWN TO YOU! You’re a parasite. A leech. A good do nothing lazy entitled waste of space. #JohnsonOut

  • Learphollach Eoin De Héatún (@Learphollach) reported from Neillstown, Leinster

    @BorisJohnson @virginmedia @O2 What network are you on?

  • JessyBr72807283 Jessy Brown (@JessyBr72807283) reported

    @VMO2News @O2 @virginmedia Poor service. I have to reboot my hub every night. That's what £90 a month buys you, rubbish
