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.
As a suggestion, check a phone number before you call it back. Many times calling back an unknown number leads to more calls. Unknown charges on your phone bill. Being tricked into pushing numbers, which you have no idea what it has done to you, or your phone.
