Sim never arrived, took me 5 days to get to speak to someone on live chat to cancel my contract in the 14 day cooling off period. I was assured the sim was cancelled, and never used, I was assured I would not be charged anything anD promptly (thankfully)cancelled my DD anD today I get a ‘final bill’ for £5.30?? For a sim I never had?? I have the live chat transcript where I was assured there would be no charges.
