  • CandiceVigario Absolutcandy (@CandiceVigario) reported

    @O2 It would be a great summer abroad if the data I paid for was provided to me! Customer service is poor, the app merged with Virgin is slow and unreliable and there is no breakdown of data usage. My data due disappeared on the renewal date and customer service can’t explain it!

    @O2 @O2 I’ve recently switched my business phone from Sky and now have no signal at all. I can’t call or access support, and your chat system isn’t helping. I’ve been on hold for over 35 minutes. Please can someone assist urgently?
