  • MahlerRehab SkepticalClassics (@MahlerRehab) reported

    First rubbish service from @VodafoneUK Now an unsolicited phone call from @O2 which was both baffling and quite unnerving. The caller got my name wrong & didn’t tell me why they were calling. When challenged they quoted extensively regarding my activity on the company’s website.

  • WrightShaun_ Shaun W. (@WrightShaun_) reported

    @O2 why do I have a purchase limit on my account I've never had issues before when purchasing my o2 account

  • KatieClaw Carol Graves (@KatieClaw) reported

    @O2 unbelievably poor customer service. Used a dongle which I asked specifically for 2 weeks. Asked what I had to do to cancel. Now find I’m being charged. And customer services hung up on me.

  • JIT_arakeen Jo (@JIT_arakeen) reported

    @O2 No thanks. Im happy with Vodafone. Been a year since I switched to Vodafone from o2 I always have a good signal and don't need to listen to lousy excuses for lack of signal coverage.

  • poppyjayhughes Poppy (@poppyjayhughes) reported

    @O2 how can I have full bars and 4G signal but everything takes ages to load. Signal has been so poor recently

  • mccc123bacardi martine cohen (@mccc123bacardi) reported

    @o2 (what is happening with your network) calls continually dropping since your merge with Virgin...... And outgoing calls having to ring numbers twice to get through

  • J0lly_r0dg3r Richard Thompson (@J0lly_r0dg3r) reported

    I can honestly say in all my years as an @O2 customer I have never had such poor customer service as I've received over the last 2 days, to the point I was going to cancel my contract. Do @O2 train anyone in their products??

  • MatthewPetts90 Matty Petts (@MatthewPetts90) reported

    @O2 are you having issues in WF4?

  • terrybutler4 Terry B (@terrybutler4) reported

    Forgot about how terrible the Internet is on @o2 when using mobile data.. Change of provider is required.

  • Bluebird_McCord Honor 🏴󠁧󠁢󠁳󠁣󠁴󠁿🍡 (@Bluebird_McCord) reported

    @O2 need to call me back before I actually lose my **** with them! Bill is paid! Give me my damn services!
