Telkom with their anauthorized debts must fall

I know Telkom won't respond but I think the public needs to take action. Telkom is ruining clients credit scores, but they clearly don't care. We have a data contract with Telkom. My account was debited since inception. Last month I get a statement showing my outstanding balance as R2216.00, I immediately phone the Customer Care line who assured me that the error is on their side and will be rectified. However, month-end guess what they debited my account with the R2216.00. The debit order was returned, I made a manual payment. Can you believe it they debited me again on the 16/03/19? I phoned the customer care line who is trying to convince me my account is in arrears. How can your account be in arrears if your contract is for R450 and have it for 3 months? Surely there must be something we can do as the public, with Telkom and their unauthorized debits. Clearly, there is a lot of people with the same complaint
