These people are insane!,...They call at all hours never leave a message, are very crypric in the conversation, and basically are a low budget medical collection agency. They cannot substantiate any claims with any written evidence or verification of any monies owed and to whom?, when the alleged debt incurred?, where the debt originated ?...or any supporting facts to substantiate any claims...be careful, I think this is some sort of cover for a confidence game of some sort.
