Cell C taking my cash !!!!

Cell C continue to take money off my account despite their " contract" , sold under false pretences, did not last 2 days as the was no connection/ reception in my area........... Took the router on 7th January, cancelled on 9th January !!! About 50 emails, maybe 45 phone calls etc etc they still take money which is really *****ing!!! Sneaky too as each debit is a different amount.
