Who called from 6575335955

A woman asked for me several times by my first name, did not say who she was, just kept loudly asking on the answering machine for me.

This number called 5 times yesterday, and 3 today. It's calling my fax line, so no one picks it up.. can not understand why they keep calling, that fax tone would burst an ear drum.  I have no outstanding debt, at least not that I know of..and if there were something it would be over 10 years old.. so it can't be that. we are on every do not call list .. people need to just stop
