This is a cell phone number. My 9 y.o. daughter answered the phone and said a man on it was breathing loud and not talking. When I took the phone the caller hung up on me. I called it back and got a message that the voice mailbox is full. If they call your home they have your address. I am signing up to take a firearms class this week.

"Hello, this is Walter with Reliance Duct and Carpet Repair.  How are you today?"

caller said they were reliant air duct cleaning

said they were a carpet cleaning company. I tried to call it back and states mail box is full, and cannot take message. my elder mother, made appt to have rug cleaned at 3pm. I am trying to cancel it.
I am worried!
