I 've been working with American Medical Collections company to facilitate the resolution of some laboratory charges. In this I have asked on XXXX separate occassions to be called after XXXX pacific time during which I 've worked with them on several tactics to resolve this. They continue to call me during working hours despite this communication and have been push XXXX. 
The billing problem originally occured because the lab I was scene at did n't validate my address or my insurance info. I went to collections without ever receiving a bill or phone call. Once in collections, I requested the original biller 's address and my account number and sent a photocopy of my insurance card so they could bill the correct insurance. 
AMC left me alone for several months while we waited for this to resolve the issue. Apparently my letter was ignored because I received more calls recently ( again, during my working hours despite the notes I asked put on my account ). 
The last polite call I received said they would mail me a form so I could forward it to the insurance company myself. After XXXX I have not received the form and got more pushy calls.
