    @O2 disgusting treatment from o2 again took £205 out my bank without authorisation and cancelled my Apple Watch and never told me call customer service and these people are a different breed of nasty horrible horrible company to deal with

  • ethorpe1950 Eric Thorpe (@ethorpe1950) reported

    @O2 I called 0344 809 0202 at 1.50 pm on 15th December to port my old number to my new O2 PAYG sim card. Gave them all my details including the PAC code. Now 48 hours later and I'm still stuck on my old network. Not impressed.

  • arthurliverpool arthur stafford (@arthurliverpool) reported

    Ha! @O2 advising “we’re working in TS11 so your signal might come and go”….really? I’ll not notice any difference as it’s a rubbish signal period.

  • argen Bruno Belcastro (@argen) reported

    @O2 hi there, I'm expecting a SIM but the Royal Mail tracking site says my tracking code isn't recognised. Can you help?

  • Sarah94x Sarah Harris (@Sarah94x) reported

    @O2 @O2 it’s still not working as it takes me to the app ?

  • crispybd ChrisWilkinsBradford (@crispybd) reported

    @O2 hi O2, no 3G or 4G in Plymouth today. Getting increasingly fed up with no data signal; what is the issue please? This has been particularly bad this last 6 months.

  • BextorDextor Rebecca (@BextorDextor) reported

    @O2 amazing customer service calling your customer a liar and taking money out my account when you weren't meant to!

  • darrenrandsgolf darren rands (@darrenrandsgolf) reported

    @O2 absolutely awful customer service! An hour on hold to then be cut off so I got to myo2 and no agents available on messenger!

  • jasonmac85 Jason McCarthy (@jasonmac85) reported

    I’ve never known a phone service as bad as @O2 it’s shocking in centre of liverpool and on 2 bars and can’t even get on certain websites. Can’t wait to go back to @e_emobile

  • nuttyhill Patrick Veale (@nuttyhill) reported from Warrington, England

    @O2 why does your signal seem to be terrible everywhere now? Even in town centres. I know you've partnered with @virginmedia but you didn't have to share their service quality
