Double Debits and Horrible Service - Telkom Mobile

Since July, I've been getting incorrect monthly statements. I make payment and it reflects, but they still debit more amounts or load more payments to be debited. All to be told "Well, the payments are reflecting but have not been allocated" - so we are paying DOUBLE because there are problems with allocation???? Also trying to cancel our monthly wifi which has been on month to month since January, but now being told we can't. I'm so close to involving the ombudsman, it's *******!! Truly horrid service
