Very simple ... I have a bill from some XXXX that has been paid with the minimal amount that is suggested on the bill itself of {$20.00}. Payments have been consistent every month, certainly no reason to go to collection. 
I spoke with the dr. and his third party billing agency and all can not understand why this went to collection as they see consistent min. payments have been made. 
I received my XXXX call at XXXX from Synerprise XXXX regarding this bill. I said that my husband is our bill payer and I would check into it. I did just that to find that payments have been made of the min. {$20.00}. I then retuned a call to the collection agency to give them the information. I received another call this morning that shook me up terribly as the individual on the phone was threatening, demanding, cocky and rude. He actually hung up on me ending his call to me. 
I told him the same thing over and over that I have been paying the min. of {$20.00}. He asked me to call him back with the latest payment information. I said I was driving and that " no '' I would not do that as he can call his customer and find that out himself and there is no reason for him to even be calling in the XXXX place as again I said that payments have been made by with the min. payment. He mimicked my " no '' with an emphasizing sure surprise that since I would not call him back with the info he requested he would send me to collection that would wreck my credit and asked me if that is that I wanted to happen. I said that I will then just get an attorney as there is no reason for him to be calling me and he said " good luck with that ''. He was rude, demanding, and insensitive to the fact I was driving as I stated to him that payments have been made and that he was telling me a lie that I owed $ XXXXwhen in fact I knew the bill was down to {$28.00} and change. He was cocky in is presentation and conclusion when saying " have a nice day '' and hung up on me. This was XXXX XXXX at Synerprise. I was shaken terribly that when I got into work I called the Dr. XXXX who was very kind and then his third party at XXXX billing - XXXX. She apologized and could not understand why this went to collection. Just bad.
