    @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

  • 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

    @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

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

  • 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.

  • sophiaioannab Sophia Ioanna (@sophiaioannab) reported

    4 months without a phone and for the 8th time I’ve just been told when the problem is fixed @O2 will compensate me, I don’t want compensation I want a working phone.

  • bluegaschris chris fear (@bluegaschris) reported

    @O2 How about sorting out your existing customer problems

  • naffynathan Nathan Everitt (@naffynathan) reported

    .@SkyHelpTeam So no broadband or 3/4/5G in Great Yarmouth area. Resorted to texting family members to find out information. Your website - nothing. @O2’s website actually says there is a mobile issue, yet yours doeen’t! Your customer service was pathetic over the phone.

  • peterbr92798348 peter breen (@peterbr92798348) reported

    @IanGriffin63 @EnglandRugby @O2 Displaying skills behind the gain line is a recipe to get smashed. England were poor last season because of our lack of powerful runners off 9 and in the centre. Someone has to regularly dent the opponents D line, in order the shorten that line and thus create space.

  • Nacnan1873 Nacnan (@Nacnan1873) reported

    @O2 How about delivering the Apple Watch I ordered nearly 7 weeks ago absolutely shocking service and absolutely no communication 😡

  • ace_7744 Michelle Price (@ace_7744) reported

    @JefferyBeaker @O2 @virginmedia I have the same problem, can't do anything that requires online connectivity. Keep getting the same replies off them. Virgin media sucks 😕

  • alexjones2018 AlexJones (@alexjones2018) reported

    @daviddunninguk @O2 Still many areas in North Yorkshire that have no phone signal.

  • CAPaulc089 Paul (@CAPaulc089) reported

    @O2 why are you ******* crooks saying my brother is in arrears for a switch you acknowledged you had back? He returned it + phoned more than once + you supposedly couldn’t find it on system yet it’s on his showing arrears. I’m gonna bad mouth you crooks as much as I can. Sort it

  • Kat19981995 Kat (@Kat19981995) reported

    . @O2 Still no update on my complaint was told 48hrs maximum Monday for a management call back still nothing. Complaint team haven’t called. Oh and you asked me to DM you but also done nothing with that either. Does anyone actually work for o2?

  • Violetsky85 Violet (@Violetsky85) reported

    @O2 my £10 credit is still not issued this absolutely shocking customer service - I tweeted that the credit code did not work over a week ago and several people from your customer service team have messaged me asking the same questions.
