I had an issue with billing, and emailed customer care immediately, after a week with no reply, I resent my email, a week further on, I phoned, spent 30 minutes on the phone being told incorrect advice, and that the manager would ring when he started his shift - he didn’t and he sent me a factually incorrect email - to which - guess what..... no response to my reply. Can not complain about the gear, but the customer service is some of the worst I have come across. Deeply disappointed and pretty irate as m6 problem is still not resolved!
