They called my house and spoke to my 17 yr old son, I think they were a home security scam.  He didn't understand them, so he hung up.  They called three more times and he hung up on them.  When they called the 4th time I picked up and said "Are these the same people who have called my house 4 times in the last 10 minutes?"  The person on the other line (male) said " If you didn't want it, you shouldn't have hung up on us"  When I hit redial, they didn't have the guts to pick up the phone (they picked up the first time and wouldn't talk to me). Non-profane words escape me.
