  • 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!

  • 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!

  • AEgbuonu ARIBBUZZ (@AEgbuonu) reported from Welwyn Garden City, England

    @O2 sort your cancellation team and phone problem out. #poorcustomerservice

  • RaviDheer Ravi Dheer (@RaviDheer) 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.

    @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

  • 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

    @O2 How did this shit happen

  • 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

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

    @O2 are gonna have to either offer me an amazing deal or sort out this horrendous signal issue. How can I not load a twitter video when I have a full 4 bars of 4G signal

  • willowswarlok Wayne Adams (@willowswarlok) reported

    @O2 I have been unable to get 5g on my iphone 12 in my area since having my phone. I barely get 2 bars of 4g. Apparently due to a mast being down…for years. I just had a message on my phone saying 4g has been deactivated on my device…and now have 3g. Absolute joke

  • ynoyrbates Auntie Bry (@ynoyrbates) reported

    @O2 I want to pay off my device plan and move provider because of poor network coverage, is this possible to do on the My O2 app?

  • FOY4EVA ❤Miss kitten❤️ (@FOY4EVA) reported

    I’ve been an @O2 customer service for 15 years. For the past 10 they’ve requested for me to upgrade and I’ve not needed to. Then agreed and they have no clue how to process orders. Shocking!

  • LangelaanM Michelle Langelaan (@LangelaanM) reported

    @O2 Still waiting for you to help me out

    @O2 in the middle of explaining I didn’t have time to discuss upgrades and asked for information to be emailed instead and the person who rang me, hung up! What amazing customer service! Could someone contact me about this please?

  • NormaShippin Norma Shippin (@NormaShippin) reported

    @O2 Also told me i cannot just cancel the order and go into a shop. This is like slipping into a parallel universe and unlike any other dealings with O2
