UNAUTHORIZED DEBITS!

THIS BUSINESS HAS DEBITED MY ACCOUNT ON BEHALF OF TELKOM! THEY HAVE NO AUTHORITY FROM ME TO DEBIT MY ACCOUNT! I SENT AN E-MAIL TO THEM REQUESTING PROOF OF ME AUTHORISING THE DEBITS BY THEM! TO DATE I RECEIVED NO RESPONSE. THIS MONIES WAS NOT OWED TO TELKOM. WHEN I LOOKED AT PREVIOUS MONTHS I NOTICED THAT NUDEBT HAVE BEEN TRYING TO DEBIT MY ACCOUNT FOR A WHILE NOW. I ACTUALLY TRANSFER ALL MY MONEY INTO ANOTHER ACCOUNT BECAUSE OF UNAUTHORISED DEBITS BUT SOMEHOW THEY MANAGED TO DEBIT BEFORE I COULD TRANSFER THE FUNDS OUT OF MY BUSINESS ACCOUNT.
