most likely a debt collector, they never leave messages. they call me too and never leave messages, one time I answered and hung up on they because they pissed me off.

Got this call early morning. WOKE ME UP!! I didn't answer as didn't recognize the number or name on caller ID. When the answering machine came on...they did NOT  leave a message,  I get far too many such calls every day. I sure wish there was some way to stop these annoyances.  I am old and  they upset  me!!
