Extremely dangerous do not answer...these people will claim they are your doctors office or school or any other private place like that by accessing your files illegally and then claim they are that, while in reality they are collection agency and quite a useless one. I called them back and tried to talk to someone and they keep hanging up the phone on me. In my opinion, if they truly have a claim and there is an unpaid bill somewhere, they should tell me who that is so I can pay it, not lie or play cat and mouse with me. THIS is a scam!!!
