Medical Business Bureau Debt Collection Complaint

Medical Business Bureau Debt collection department,

Medical Cont'd attempts collect debt not owed Debt was paid Illinois

I have already disputed the amount this company is attempting to collect from me. I do not owe this amount since my insurance paid for the very same claim this people are trying to collect on. I need them to prove what they are saying, and I need them to stop their harassment. I waited over 2 months to take on the treatment, because I was not able to take it until it was approved and paid by insurance.
