MTN unable to help me report ***** in my account

I called MTN to inquire about billing in my account for two numbers i do not recognize (***). The guy who helped me asked me to call ***** department to report the issue. First he provided me with the incorrect number, then had to google the correct number and the guy who picked up the phone said i need to call 808 and request to be transferred to Internal forensic department. I called 808 and the guy who picked up told me its for the first time he hears of this department. i need to have the numbers been billed under my account cancelled and MTN reimburse me.
