MTN steeling money - random debit order

On the 30th of November I received an sms from my bank that an amount of R946.51 was DEBITED from my account and I don't even have an MTN account! How did you get my details and how can you just take my money?? I have been in contact with Alice van der Merwe - I have sent 2 emails following up on my email and I haven't had any feedback yet. You are requiring an affidavit from me and my ID - I have sent my ID through and stated in my email that I have NEVER been associated with MTN EVER. You say you cancelled my debit order and suspended the account - but how can you do that without any of my details or the fact that I don't even have an account with you??? This is really ********* to just take my money and then not to get back to me. It has now almost been 3 weeks and still I have no feedback from you.

THIS IS *****!!!!
