    @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

    @O2 I'm sick to death of your network. I'm trying to pay you and I can't. Now I'll wait for some fool to contact me. I give up with this pathetic network.

  • 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

  • PaulWRamsay #HellomynameisPaul (@PaulWRamsay) reported from London Colney, England

    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!

  • jodyrandall Jody Randall Esq. (@jodyrandall) reported from Broxbourne District, England

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

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

  • CraigFamilyBlog Hayley & Gavin (@CraigFamilyBlog) reported from St Albans, England

    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!

  • 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

  • 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

  • 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.

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

  • wayneede Smush2 (@wayneede) reported

    @O2 How do I cancel a iPad Airtime plan of £11.02 (I know not a lot) as the iPad only gets used on Wi-Fi and device plan was paid of ages ago. I don’t want to cancel my phone but not in need of anything at moment. Just don’t want to pay for the iPad Airtime plan anymore.

  • ruthhumpherson LifewithRuthieH (@ruthhumpherson) reported

    @SkyHelpTeam I appreciate that and have received the article and if all people had the same issue that is one thing but given that @O2 users and other networks have data on @My_Metro why can’t all networks in the interest of safety and well-being?

  • bradstwo bb (@bradstwo) reported

    Outrageous service by @O2 . Called on 4 separate occasions to try to cancel my contract and cut off by the line every single time. All while I’m being charged for cancelling without calling! A joke of a customer service, absolute joke.

  • victorique1984 Victorique (@victorique1984) reported

    @O2 just had a scam phone call from someone pretending to be you trying to give me 50% off. But once I said that you never phone you just text and this is a scam they put the phone down. Just thought you should now.

  • Sharonshutt Sharon shuttlewood (@Sharonshutt) reported

    @O2 please help , received invoice reminder for sim account I have never set up , used or received , can’t verify my account over the phone as haven’t received email verification o2 said they have sent me! Spoke to completely unhelpful Rehan at 02 who can’t help. 😩😩

  • mdw012 Marius (@mdw012) reported

    @O2 Abslutely worst mobile service provider! At the saddest time of my life with my Mom passing away I have zero signal. What's the point of telling me to call a customer support number if I don't have any signal. Frustrated

  • FiorellaWyn Fiorella Wyn (@FiorellaWyn) reported

    @O2 Seriously i just need help changing my direct debit date, it really shouldn’t be this hard

  • FiorellaWyn Fiorella Wyn (@FiorellaWyn) reported

    @O2 Yeah but ive literally had to call you out multiple times on Twitter to get help. Contacting a service prvider really shouldn’t be this hard or stressful

  • rachtwins1 Rachel Mcloughlin (@rachtwins1) reported

    Yesterday I spent 3 hours on an appalling web chat trying to upgrade my daughters phone. It was excruciating. To round it off she was then turned away from the store as I wasn’t with her to collect phone. I have 4 phones on a contract with you tbh I might cAncel the lot #o2 @O2

  • AdamPrtn Adam (@AdamPrtn) reported

    @GroundedTech @O2 I mean yeah, I snapped at him and it resulted in him getting my full anger but damn, what a way to treat a customer.. Ah well, good riddance tbh.
