Charging my cancelled contract.

Cancelled my contract last year May, I used it for 2 weeks and decided it's not for me.I put it back in its box and are still waiting for them to come and collect.They are still charging me,my account is now on R1700. I spoke to one of their clerks and he said I used R200 of data end of June last year. I told him I was in Namibia with my family on holiday how could I have used it? Hi Jacques de Waal, Thank you for contacting rain telecom, Hope you are doing well.
