MTN ***** Dept unable to contact.

I am trying to report a ********** transaction on my account and have been told by customer care to email an affidavit to ***. When I email that address I receive an out-of-office reply telling me to email *** which is exactly the same address. How am I supposed to report this because sure as hell MTN will deduct that ********** transaction from my bank account come to the month-end? I have also tried filling an online ***** report but after filling the form in it will not send.
