MTN *****!!! RE: ********** Contract [#***]

I want to make MTN and other businesses URGENTLY aware to what has happened to my business. Monies was debited off my account in December 2021 by MTN even though I have NEVER opened an account, signed a debit order, given bank details or company info or telephonically agreed to a contract. Our bank reversed debit order but it happened again in January 2022 debiting double the amount! I contacted the customer care line and they advised me to send an email with an Affidavit (Stamped by the police), my ID and letter requesting to stop the contract and investigate the ********** case. I received an email with a reference number and that the matter would be investigated. BUT triple the amount was debited off our account on the 2 March 2022 of R 10 884.28. I phoned customer care again and they could not help me! How do I get this resolved before end of March as they will probably debit my account with four times the amount????
