Investigation for unauthorized debit orders

good day

This is the second review and no response have been communicated to me. I been having unauthorized debit orders from my standard bank account with a Telkom Reference, i dont have and never had an account with Telkom since June and on the 27 July 2018 i logged a complain and submitted an affidavit at the Telkom branch in Wonderpark, case number: ********** 2. i also went in September to check for the Status of the case but i was told to log in my number and i will have automatic call back. This debits started deducting R100 in my account and then R1500, R2000, R2500 and also R4000 since June and they these debits take place on the 15th, 20th,26th and sometimes the 30th of each month from June. This have affected my finances and casued me financial disorder and strain. In November this unauthorized debit orders have escalated to R10 000 which happened on the 15TH and the 20th. This have caused more than 10 unpaid fee items charges and other bank charges. Th bank refuse to reverse the charges as they say Telkom is a big company and the advised me to receive confirmation from Telkom that i have no agreement with them but Telkom haven't responded to my complains and my bank account continue to be overdrawn. please assist
