On my credit statements show that I have not paid Medical Business Bureau {$160.00}, this was reported again today, XXXX XXXX, XXXX after I got off of the phone with them to let them know it was paid at the end of XXXX, XXXX - They see that the account has a {$0.00} but are still reporting to collections I have a balance and have refused now, 5 times to provide me with a paid receipt as they say that is " against policy '' - I have never heard of such a thing - I ca n't have proof of payment? I need this closed and taken off of my credit bureaus.
