    @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 Is incoming calls down as I have had so many missed calls from people who have had to call on landline not good for business

  • 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

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

  • 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!

  • 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!

    @virginmedia @O2 We have been having our broadband turn of completely once a day and a reboot doesn't fix it. We have to call your help line for them to reboot it. A engineer was booked last night and now has been cancelled??

    @O2 Hi there O2! I am trying to speak to someone to get my PAYG SIM replaced as I lost it! The O2 app won't allow me to login to raise a Live Chat either! Can you help me please? Thank you.

  • JDHudson19 JH (@JDHudson19) reported

    @O2 Trying to speak to anyone at O2 customer services is impossible. Going round and round in circles on the website and app. Everytime I think I will get a number or be able to message a real person I am redirected to a help FAQ page which doesn't help.

  • DavidMcAct David McCarthy (@DavidMcAct) reported

    @O2 trying to get a copy of my latest bill but It just says something went wrong and your technicians are on it on both My O2 app and the website, is this an everyone problem or a just me problem ?

  • EoinMcCann86 Eoin (@EoinMcCann86) reported

    @O2 I left Vodafone to come back to O2 and now I'm regretting my decision, I got unlimited data and the speeds compared to what I had with Vodafone is a joke, I can't cancel because I'm outside the 14days, I'm getting 2mb on speedtast and the signal is awful. 21months left 😭
