PAID UP LETTER

Hi i phoned telkom because i was behind on my account, i tried to make small payments of r100 sometimes more and less, just to let it go doen last month i contacted them to get a settlement amount the guy gave me the amount at which i paid two days later they said i must stil pay a r45 and now im waiting for the paid up letter, i paid on the 17th of last month already they said it takes 7 days?

Everytime i call its a different story now i got an sms from attorneys saying i owe r5300 amd something? Which is double what i owed?

Stil no one can give me a paid up letter, which i think is unfair because as far as i remember a consumer is entitled to a settlement letter and once its paid up he can get a pid up letter according to the nca?

Some help please
