Sick and tired

Im tired of telling MTN the same thing over and over again. I do not have an account with you guys. you keep saying you will investigate but you never do. Im getting tired of messages that I need to settle my account or make repayment plans. It's been 4 years, when are you gonna investigate and leave me the hell alone? geez! how many times have i sent affidavits and copy of my ID and signatures, will this ever end???
