I was enrolled with NABL from April 2010 to July 2010. My family had some medical issues. NABL only paid one bill. Every time I call, they said to call back in two weeks. This went on for awhile. Then eventually they said they haven't received it. Now it was turned over to an attorney who requested the CMS 1500 form. I submitted fifteen forms with the bills and faxed each one separately a month ago. The latest status is the attorney never received them.
