Who called from 5595240671

Called my cell phone and when I answered, I said "Hello?" a couple of times before they just hung up.

They called my boyfriend a moment ago, it was a female named barbara who said she worked with some company about debt, and wanted to know if we wanted to apply with them. We said no ( because we have no debt) and asked what company she worked for, to which she ignored and never answered, but she kept saying great! We'll sign u up. And even if we said no, she took it as yes.

This number keeps calling and when I answer, they dont reply and hangs up.

i don't answer callls from unknown numbers... they left no message...
