No message has ever been left after multiple calls. No idea who they are or what they want. I do not get calls like this on my cell phone unless someone mis-dialed.
Got a phone call from this number wanting to sell me an extended warranty on my car...when I told them we trade our cars every two years before the warranty is up and asked how they got my cell phone number they hung up on me. Tried calling it back and it says its disconnected.
