DOUBLE billing still not sorted out

Please see: https://www.hellopeter.com/cell-c/reviews/double-billing-not-sorted-out- **********

I was contacted, as mentioned, but, since 20 Nov - 23 Nov 2018, apart from that one phone call, no contact has been received from Cell C - I've received no indication that my query is being attended to (after the phone call received) or that any resolution has been reached.

This accounting error (read DOUBLE BILLING & refusal to adhere to cancellation notifications) has received no attention (seemingly) from the accounts/billing department at CellC - in the meantime, If I don't pay double, I stand the risk of having my service suspended as well as being handed over for debt collection... How long must I continue to pay DOUBLE? I do believe that 10 months+ is not acceptable.
