The ONLY reason I answered the call is because I was expecting to be getting a call from someone that I did not know their number.
Automated caller. Had the voice down pretty good. Didn't catch it was a machine at first. Asked if my name was Michael, etc... Proceeded to say I won something... I immediately hung up.
I've gotten calls from this number as well as 515-528-7968. If I pick up, there's nothing on the other line, then it hangs up, if I don't pick up, the caller doesn't leave a message.
