Complaint Review: Inland Cardiology Associates

My original bill after heart surgery was several thousand dollars. I have two medical plans. I received notification that the provider (Inland Cardiology) had accepted the Medicare and Blue Cross payments as "Payment in Full" and nothing more was due on the account.I had written documentation from Medicare and Blue Cross stating this provider was "PAID IN FULL". Nevertheless, they wanted $93. I got nasty letters, phone calls, threats to ruin my credit (keep in mind the fact I have a heart condition and really don't need the stress). Finally they turned it over to a collection agency. They called, they sent nasty letters, they threatened to garnish my wages (even though they can't since I'm on Social Security). I sent the collection agency the written proof that this bill was "PAID IN FULL". Nevertheless, I have a negative mark on my credit report that effects my credit rating. The provider was paid 10s of thousands of dollars by insurance.Did they need to ruin my credit for $93 ??
