    @O2 any chance of a phone signal Guys? No improvement round here (TA14) in a decade. Unbelievably poor…

  • EwanEaston Ewan Easton (@EwanEaston) reported

    @O2 Tried everything that’s recommended on the o2 forum. Still not working.

  • malsyboy Al (@malsyboy) reported

    @O2 further to my earlier tweet, o2 complaints are terrible too. No signal in Portsmouth dock, should be 5G getting E (c.1994). Should of stayed with EE!

  • __luuwilliams luu (@__luuwilliams) reported

    @O2 clearly don’t want me to pay my final bill with them, have attempted to do this several times online and through the app, no longer recognises my details. Also tried ringing customer services and have been cut off every time after being put in a queue. Glad I left them now 👍🏼

  • catherineheb Catherine (@catherineheb) reported

    @O2 I’ve had no phone signal for 24 hours, your help option in the o2 app just takes me to an online link to tell me a mast isn’t working properly. Need to speak to someone ASAP as can’t send or receive texts or calls!

  • nirouabs Niroshia Abdulla (@nirouabs) reported

    @O2 what is going on with your customer service. Cannot get anyone on the phone or live chat. Need a replacement sim for my elderly dad. Please sort this. I have been a customer for over 20 years. This might change shortly along with all 8 members of my family.

  • edupayton Miss Mylroie (@edupayton) reported

    Just spoken to the rudest advisor on the phone whilst trying to cancel phone contract with O2. @o2 I suggest you have a listen back to the call as a demonstration on how NOT to talk to customers

  • UKCopHumour UK Cop Humour (@UKCopHumour) reported

    @GorillaoJustice @O2 Merged with virgin media! Since the merge, my signal has been bloody awful and in some areas that used to be 4G have now dipped to 3G. The signal has been so bad now thinking of changing contract

  • villetaone Alex (@villetaone) reported

    @O2 Sucks, unfair that some people can get good deals but long existing customers can not. Buuuu O2

  • fasculineking Khaz. (@fasculineking) reported
