    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!

  • 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!

  • Kami2k10 Kamiioo (@Kami2k10) reported from Luton, England

    @BBCNews @O2 worst coverage ever no solutions. The network towers always down but yet I'm still paying 55£ p.m i have no choice but to pay!! #ripoffbritain #conmen

  • stourdave Dave (@stourdave) reported from London Colney, England

    @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

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

  • WickhamofWare Jonathan Flood (@WickhamofWare) reported from Stevenage District, England

  • 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

  • banafshbanafsh banafsheh (@banafshbanafsh) reported from Waltham Abbey, England

    @TazPDN @O2 So sorry to hear that ,#o2 is really bad, I'm with Vodaphone and they are much much better . Hope all get sorted for you x

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

  • AKMPower1 AK (@AKMPower1) reported

    @O2 the worst customer service imaginable!! I have been a customer over 20+ years and been sold a watch contract that doesn’t exit! Also took a second contract which was not honoured! Been spoken to rudely by management in South Africa, 3 weeks and a still pending. #Horrendous

  • Bluebird_McCord Honor 🏴󠁧󠁢󠁳󠁣󠁴󠁿🇺🇦🌈 (@Bluebird_McCord) reported

    @O2 Well that failed. Will attempt again later. I’m currently in hospital and trying to figure out how to sort my bill but the signal is terrible in this area 😔 Thank you for the information though!

  • siannnyyy26 Donaldson🏴‍☠️ (@siannnyyy26) reported

    @O2 Image phones lasting longer than 2 yrs??? Then we wldnt have to . Phone from you after 2 yrs speaker went battery life was crap and funny you said your eligible for upgrade. So we spend over 600 on phone for 2 Yr. My old bt cellnet Mobile still works all these yrs later

  • JTweetz14 J (@JTweetz14) reported

    @o2 if I carnt have a device that is compatible with your network, then by all means you should provide me with one. I'm in contract with you and I have a device that doesn't work with you. Very strange. I've been a loyal customer for over 10 years!

  • WrightShaun_ Shaun W. (@WrightShaun_) reported

    @O2 can I pay off and cancel on of my numbers online or do I need to call

  • Ceris8 Ceris (@Ceris8) reported

    @O2 @BWallaceMP Smart meter doesn’t work ( don’t need that right now!). Why on earth is there an access problem?

  • j13hb J. Silva📍🇬🇧 (@j13hb) reported

    @O2 It’s not happy Monday if my service is down fit the whole weekend

  • Ceris8 Ceris (@Ceris8) reported

    @O2 Finally, you are talking to me. Your customer service is appalling. This problem has been ongoing for several months now… Not being able to get access to the mast, landlord problems? This is unacceptable. @BWallaceMP

  • dunny6times Darren Dunne (@dunny6times) reported

    Is there any cash incentive from @EE to terminate contract with @O2 in the interest of them getting a new customer with a phone that actually works in an area when there is 100 people. Blackpool last night with the kids and can’t even make a phone call.

  • missiles22 Tracey (@missiles22) reported

    @ChefWayner @O2 And those of us waiting for yet another 'network issue' to be solved and my DM's to be answered. It's clear that O2 don't give two figs about their customers 🤬
