MTN COMPLAINT

I have never had a contract with MTN a debit order was deducted 2021/12/31 which I disputed and reversed and informed MTN that I am not a client of them nor do I have a contract, they also do not find me on their system so they suggest I should phone 083135 and speak to a consultant… guess what there is no option to speak with a consultant and you have to provide your MTN cell phone number which if you MTN have been reacting to my numerous emails to you, you will realize I AM NOT YOUR CLIENT, I DO NOT HAVE A MTN CELL PHONE NUMBER !!! Another debit order deducted today I sent emails again, last response received is that I have to supply them with a certified copy of my ID, and my residential address and my signature before they can investigate a case of *****.. AGAIN I AM NOT YOUR CLIENT NOR DO I HAVE AN AGREEMENT OR CONTRACT WITH YOU WHY WILL I SHARE MY PRIVATE AND PERSONAL INFO? Clearly if I do not have a contract with you and I have disputed and reversed the 1st deduction why would you keep on instating a debit order on my bank account… Please just explain to me how a issue like this can be resolved !
