Product: Debt collection

I was contacted on XX/XX/XXXX by a female representative with Amerassist at ( XXXX ) XXXX. She said I owed a debt of approximately {$3000.00} to their company. I had not received any medical bills close to this amount, but had an issue with a bill from this same company being bounced around between XXXX XXXX XXXX and my insurance company in XXXX. I was contacted by the company in XXXX and it was paid in full. I explained that I had a paid in full letter and did not owe them anything. She became very hostile with me. I explained that I worked for a bank and told her how she was treating me was against the law. She then said " Now, I know where you work! '' I perceived that to be very threatening, although I did not disclose the name of the bank I work for. When I asked her for her name, she refused to give it to me and said she was ending the call. She hung up on me. 

Later on XX/XX/XXXX, I called XXXX XXXX XXXX ( same company as XXXX XXXX XXXX -- the parent company is XXXX ) to complain to them about how I had been treated by the collection agency that works for them and to inquire if I had any outstanding accounts open. My daughter has severe XXXX and has her XXXX XXXX lengthened once every 6 months. The person I spoke to over the phone could not find any open accounts under my name, but referred me to XXXX XXXX, who directly handled their relationship with Amerassist. XXXX called me on XX/XX/XXXX. She went through their records and found an account from XXXX that I owed {$150.00}. She found that I hadn't received a bill because my address changed ( my name did as well, which is why the 1st representative didn't find this account initially ). I took care of the balance immediately over the telephone. She assured my that all of my cases were closed and that Amerassist would not contact me again. However, Amerassist did call me again on XX/XX/XXXX, XX/XX/XXXX, XX/XX/XXXX, and today ( XX/XX/XXXX ). XX/XX/XXXX and XX/XX/XXXX are the only times Amerassist left a voice message. After the XX/XX/XXXX voice message, I reached back out to XXXX to let her know I had been contacted by the collection agency again. After the voice message today ( XX/XX/XXXX ), I called Amerassist directly. I was transferred to " XXXX ''. When XXXX answered the phone, I recognized her voice as the person who treated me abusively on XX/XX/XXXX. When I told her that I spoke directly with XXXX at XXXX XXXX XXXX and was assured I owed Amerassist no money, she told me she wasn't going to argue with me and said she was ending the call. I called back and requested to speak to a supervisor. XXXX XXXX is the who I spoke with next. He said that he looked into my file and that XXXX had taken my number out of their system and I would not be contacted again. 

XXXX called me back today ( XX/XX/XXXX ) and informed me that XXXX XXXX XXXX had notified Amerassist twice that all of my accounts had been paid in full and to call her back if I am contacted again. 

I was contacted by 2 different telephone numbers -- ( XXXX XXXX XXXX and ( XXXX ) XXXX. As I stated before, my daughter has significant medical needs and I work very hard to make sure all of her bills are paid in a timely manner. This one physician group has an extremely slow billing process because they go back to my insurance company so many times with follow up claims. This has been very frustrating and I want Amerassist to  stop harassing me when I don't have any open collection accounts. 

Thank you for your help with this troubling matter.
