    @virginmedia @TheBHF @O2 To be fair defibrillator great idea, but I'm having to right this as your customer service department has to be the worst ever, I've an over heating hub 4 which needs replacing and nobody wants to help, I can't even get someone to let me leave

  • jamesBl4c James Blackman 🌹 (@jamesBl4c) reported

    @Daisiver29 @O2 Yep... and when I go to my clients with software licenses and say we're putting your fee up by 5% they throw the teddies out the pram and tell us to **** off.

    @MrColinOwen @O2 @GarethTurpin Pretty soon we’ll be paying the increased price for a phone we haven’t even received 🤬 2 months waiting for an ordered upgrade and no help whatsoever from the shocking o2 customer services

  • jane03832094 jane (@jane03832094) reported

    @O2 That’s the only answer o2 ever give!! Over an hour on the phone holding every week to speak to you. Promises of callbacks and it never happens. Your treatment of existing customers, PAYING for something they DO NOT HAVE is appalling and I am at my wits end with you. @Ofcom

  • Cvt116 CB1 (@Cvt116) reported

    @O2 @o2 Here's some more reasons not to love you: 13.4% price increase. And a network with very poor coverage. I will not be renewing my contract. That way, you won't be able to fleece me any more. No way to contact you. Just some inane 'virtual' assistant. Dreadful!

  • ABOT1872 Camy (@ABOT1872) reported

    @SamMill01557985 @O2 Probably the worst signal I've ever had from any provider as well

  • ScubaJeff904 ScubaJeff (@ScubaJeff904) reported

    @O2 are you gonna help with this? Still not updated to show my bills been paid

  • emmasiobhan22 RedVelvet 💚🤍💜 (@emmasiobhan22) reported

    @O2 There is a BIG difference between a couple of £s increase and £11 a month. That's a huge increase. Like I said I bet we see you still having huge profits anyway because you are getting extra money from all your customers never mind the fact that we have a living crisis!

  • Jimbobthon James Richards (@Jimbobthon) reported

    Greedy @O2 . Not only do you have absolutely terrible service (best you can offer at times is "WiFi calling"). Now, a nearly 14% increase for a "non existent" service. Good thing my contracts up this year.

  • the_wilko Ben Wilkins (@the_wilko) reported

    @O2 our family has 3 contracts with you and my wife and I have been customers for 18 & 16 yrs respectively. This is an absolute joke, your service has been getting steadily worse and this price rise is totally unacceptable. PS Don’t bother with your cut and paste response.
