Unauthorized debit orders by Telkom

I have a complaint against Telkom regarding debit orders that have been going off on my bank account. Telkom's been sending me sms's regarding payment for an account since 2019 which I did not open. The sms's reflect an account number and due dates for payment. My account has been debited since then every month and I kept reversing the debits with my bank. I went to Telkom offices in Southgate sometime in October 2019 to lay a complaint and they opened a ***** case and I was informed that the account will be stopped and investigated. Less than 2 weeks after laying the complaint, my bank account was debited again, I then called Telkom customer service to find out what happened to the cancellation of the account, I was then informed that the ***** case was cancelled hence the debits continued. I inquired who closed the case because the case was not resolved and they said that they will investigate but since February 2020 I've been struggling to get a response. In March 2020 alone Telkom has debited my account twice for an amount of R725 for a service I am not getting nor did I apply for. I think Teljom is taking an advantage that I once had an account with them for a laptop in 2*** and was fully paid. Now when they are supposed to stop debiting my account they continue in the name of a "new account" since they have my banking details. I've requested proof of signed documents for this new account or a telephonic recording when this new account was opened but nothing has been provided so far instead they keep forcing payments for an account I did not take. I don't have a problem to pay for a service I am benefiting from but in this case, I think and know someone possible within Telkom created this account and is making me pay for it. There's an official from Telkom who promised to come back to me by the name of Pakiso Mabaso but I've been sending emails requesting feedback with no success.
