Missed the call...if they call again I'm going to invite them over so I can see some i.d. find out who they are and have the local PD waiting to get some more info on whatever scam they are running.
Go right ahead, and for a price, they can invite other telepests to make sure your phone keeps ringing with nonsense calls in the meantime. It is fun to toy with these crooks, however, your participation is all they need to make some money off of selling your live number to other parties of scammers. They're not going to be appearing at your house.
