Telkom creates ********** accounts when they have your banking details

Good day, for the second time now Telkom has opened a ********** account on my name. I have opened a ***** case at Telkom, but they still insist on withdrawing money from my bank account until the ***** case has been resolved. I was told that such ***** cases can take months to be resolved. So while Telkom still gets their ********** money, I can't buy groceries. I can go to my bank to reverse the debit order, but that will incur bank charges and possibly create a negative credit score on my name with the credit bureau. Everyone I contact at Telkom, just tells me to wait.
