    Really bad service from @O2, having calls from a shop to pressure into upgrades, no really clarity when calling 202 to ask what’s going on-I think I need a new network!

    Gav and I have had no mobile phone service for 3 days, but I have no service to call @virginmedia to let them know! It happens far too regularly. Just spent the morning searching for a new deal. @O2 looks like the best so far!

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

    @O2 why is your 4G so bloody awful at Liverpool Street Station

  • dramattyhealy 🌜cobie🌛 (@dramattyhealy) reported from London Colney, England

    @O2 Hi, it’s been 2 weeks since i started receiving non stop calls from your call centres to get me get a plan with you, the caller said that i entered some kind of contest or signed up for this but i never did since i am happy with my current provider. This is very inconvenient

  • AndrewTRIrwin Andrew Irwin (@AndrewTRIrwin) reported from London Colney, England

    @EmmaShubrook @O2 Agreed. I have no signal at all

  • 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!

  • mrjc90 Josh (@mrjc90) reported from Hitchin, England

    @O2 not sure when your call centre in Cape Town opened but it’s been extremely painful trying to solve a simple issue..I might of been unlucky but think staff could do with some further training

  • AFCAMDEN AFCAMDEN (@AFCAMDEN) reported from London Colney, England

    @SkyNewsBreak Would cancel my contract with @O2 immediately if they did.

  • AddictiveColors Addictive Colors (@AddictiveColors) reported from London Colney, England

    @O2 I understand that carriages speed and materials do not help, but repeaters in tunnels sure would to avoid disruptions especially as they can particularly nasty to a laptop when the phone or the train is the hotspot as that side of the connection never goes down just the gateway’s

  • 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

  • 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.

  • isthatdan Dan (@isthatdan) reported from Stevenage District, England

  • TTreeks ACOWBOYINSWEDEN (@TTreeks) reported

    @StopFundingHate @O2 Please do not advertise on another media outlet intended to spread hatred. I would have to get my Mobile service elsewhere if you do. #DontFundGBNews

  • AnnielizzieSten Annie (@AnnielizzieSten) reported from Sheffield, England

    Hi @O2 I have no complaints about your service but if you advertise on GB News I will immediately change my mobile phone provider #DontFundGBNews

  • GregorBuick Gregor Buick (@GregorBuick) reported

    @O2 I've just sent a PM. If you could look in to that, I'd be much obliged. Just sea odd that I've been customer for years but can't change to a deal that you're widely advertising.

  • shaun_scannell ●phantom ferry captain #WATON #3Point5Percent (@shaun_scannell) reported

    Hello @o2 please dont advertise on, or support in any way GB News. This country does not need any "alternative" news channels. I have been an 02 customer for over 20 years, but will switch to another provider if you do. #DontFundGBNews

  • chellyscot Michelle Stevenson (@chellyscot) reported
