They called my land line today with a robocall message: "If this is Brian R---- or spouse, press 1 now. If not, hang up immediately." No option to talk to them if they are calling the wrong number.

As far as I have learned, this guy never had my number though another guy these agencies call for did have my number 2 years ago. (I've had the number a year now.)  If it is Transworld Systems as an earlier post claims, you can find their contact information on-line.
