I picked up and heard a recording asking me to press 1 if I did not receive some kind of mailing together with my gas bill. I hung up. This call came in a row with other 2 spam calls. The numbers on the caller id were different, but the problem the same--it's an unwanted call. I think the scammers have figured out that when they find a working number and a live person, they can spoof different numbers and continue getting this person to pick up the phone over and over again. That must be fun for them.
