Vodacom Terrible ITC department

Been Nearly a year since my account has been paid up. I have written several emails, made several calls. Ive been told my numerous people that it has now been sent through but still no update to my itc. The total of the account was R7000 now on my itc report it says I have to pay vodacom R7000 every MONTH. Even though its been paid up for a year next month. It just doesnt get resolved. I am even thinking of going a legal route as I am fed up and tired of calling and trying to sort this out. It is affecting me as a consumer as I cant get approved for anything now.
