  • 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

  • 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 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

  • 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!

  • jskemp76 Jamie Kemp🇺🇦 (@jskemp76) reported

    @O2 constantly have reasonable 4G displayed on my phone, however zero actual internet connectivity. This has been going on for weeks now, loads of friends have same issue. O2 just say it’s in hand. Coverage checker display very good 4G signal. Can I leave without penalty?

  • shirleybradley1 Shirley Bradley (@shirleybradley1) reported

    @O2 how difficult does it need to be to book an appointment in an o2 shop about my broken phone! I went on the book a O2 guru on the website and apparently it doesn't recognise my post code or town. Then live chat cut me off 🥴

  • HasWingsUK HasWings™ (@HasWingsUK) reported

    @O2 @GoodThingsFdn @virginmedia When you call customer service on 202 and you request to speak to a manager and they say it will be in the next 24 hours. NO CUSTOMER SERVICE. Even support message are no answered as busy. O2 Travel takes 32 sec for a 2mb picture

  • tjtrewin 🌎 TJ's Worldbuilding Resources ✨ (@tjtrewin) reported

    @O2 hey O2, I went in store on Saturday to swap my SIM to a different size for my new phone, but the new SIM is giving an error of "SIM 1 not provisioned" on my Android. It's been over 48hrs since the swap, please can you help me out with this?

  • lloseby Leigh Loseby (@lloseby) reported

    @O2 Priority on Peter Kay tickets ❌, order last night for next day not delivered today❌, no response to messages on here ❌, no email to say when being delivered but told it’s in stock ❌. Why do I bother giving you money every month. All round service is poor!
