Paid up contract

I had a contract with MTN and the account was paid up sometime in 2010. Today app**** for a contract and was advised that my contract I had with them is in an 808 status??? This contract was paid up long time ago. No corresponded or notification was send to me, they just advised that the contract is in the legal department. I spoke to a Nombulelo Mabaso she just told me my account is at legal and transferred from pillar to post. Eventually Robert Bongani assisted me and told me that the contract was paid up reference ***8. Why did MTN take so long to remove my name they listed my name incorrectly and this affected my credit profile? MTN could not even send a letter that my account was paid up. What useless service they render I will tell the whole world not to use them as they ***** people.
