from plano tx.  rang and rang.  didn't answer calls I don't know.  tried to do a reverse phone number check and it says the number is invalid.

Same here. Called and hung up. No message. Even called my cell phone and home phone

i got a call from this number and they said one company and called number back and its another company.. they knew my name.. didn't answer cuz i don't answer numbers i don't know..
