Caller called and requested ssn, dob, etc. offering to bill Medicare for back and knee brace!

called left no message  AGAIN AND AGAIN

This number has called me several time with New York,NY before the number. As I don't know anyone in front of the number I wouldn't answer the call. This was on my house phone. I called the number back on my cell so they wouldn't have my house number register as calling them back and got a voice mail about a back brace. Said if I knew anyone with back problems to leave my name and number and they would get baack to me. Of course I hung up.

Recd call offering to sell back and knee brace and apply to Medicare for payment
