    @O2 @tescomobile @actionfrauduk When I look it up on your network line, apparently phone mast isn’t working properly some of the time. Yet other times it still fails to send even when it’s working. I have no intention of changing my number but I want to know how fraudulent companies got my number.

    @O2 Sent 2 emails now tried phoning and still nothing? Any other help available?

  • g_jinal Jinny (@g_jinal) reported

    @O2 Don't forget you can make calls and send texts using Wi-Fi, which could give you clearer calls and better coverage. Find out how to get set up. Thank you for this evidence what's the point of paying for a service which never has any coverage where ever we are abloute joke!!!

    @O2 Hi I’m an existing 02 customer is this deal that you pay £3.99 a month on top of your monthly rate and you can get a new phone whenever you like or is it £3.99 plus the cost of the handset. I am assuming the latter but it’s not clear

  • NathFerguson Nath (@NathFerguson) reported

    @Brian_McLachlan @O2 Yh it’s poor I’m getting 0.87mb constantly data speed and no point in complaining they don’t do nothing to sort it, they just fob you off

  • ClanGimmy J (@ClanGimmy) reported

    One my friends is trying to set up a dongle with you over the phone. Whenever they ring 0344 809 0202 the customer service line, it transfers them to a dodgy fraud number. Any ideas? @O2

  • mattdenchfield Matt Denchfield (@mattdenchfield) reported

    @O2 Awesome, thanks! I’ve DM’d about some other errors on my account too…

  • rsby33 junior (@rsby33) reported

    @O2 please reply to my DM - need urgent help

  • Extinguisherman Dale Watts (@Extinguisherman) reported

    @dunny6times @O2 We need to get this issue known, it’s crazy paying for a service that doesn’t work. Retweet complaint using BBCWatchdog, ofcom, Martin Lewis and whichuk tags.

  • mikewakeman Mike Wakeman (@mikewakeman) reported

    @O2 how come you can’t tell me WHY I have spent hours on the phone trying to resolve an issue? And WHY you consistently promise to call me but almost always fail to do so? The question remains: Why?
