Cellc Clueless again.

Cell C! I cancelled 3 active contracts in and around May.They seem to have activated a dormant number that was cancelled over a year ago, and continued debiting me. I in turn kept reversing the payments, only to now have an adverse on my name and legal fees. I called in but Cellc are clueless here .How does this operator still stay in business .Stay away from this clueless bunch!
