    @O2 absolutely appalled at o2 customer service - how can such a big company not value customer service?!!!

  • Jay1412 Jason (@Jay1412) reported

    @VodafoneUK over 5 hours to get an issue resolved and still waiting. I think the hundreds we pay each month might have to go to someone more deserving. @O2 can you do better and not over charge us???

  • shanebroadhead Barry Cuda (@shanebroadhead) reported

    @O2 Got better signal in the middle of a forest in New Jersey than anywhere in the UK

    @O2 You having a laugh! Been trying to get working service since I moved from vodaphone last February…worst thing I ever done.

    @njvns @O2 MARCONI NEVER HAD THESE ISSUES!

  • IsmaeelFarooqi Ismaeel (@IsmaeelFarooqi) reported

    @CoralBnes @O2 Try to return this colour if possible. It has bad feedback that the colour fades after a while. It’s a new colour and it hasn’t succeeded

  • JcraigJennifer Jen (@JcraigJennifer) reported

    @O2 I ordered a phone last Wednesday. It still hasn’t been delivered. I sent a DM and was just told to contact dpd myself (I’ve had no response.) I requested a call back from O2 and never received one. My contract has all charges but I don’t have the phone!

  • EvilGayTwin Stuart (@EvilGayTwin) reported

    @njvns @O2 Kinda ironic that Chelmsford is the “birthplace of radio”. It’s like how rubbish the TV and DAB radio signal is here as well.

  • cbuzz77 Chris (@cbuzz77) reported

    @njvns @O2 Same issue in Cardiff, signal p*ss poor.

  • neenakoshal Neena Koshal (@neenakoshal) reported

    @O2 please can someone call me! Enough is enough! I can’t believe how incompetent o2 have been and I’ve had enough! And if this is how you treat your new customers it’s a definite no no for me
