I too have been receiving these unwanted calls. and i just don't answer them. they seem to be on a timer of some sort. sometimes it is as late as after 8 pm.
This number keeps coming up on our caller I.D. Fortunetly we don't answer calls we don't recognize. But, just wish these calls would stop. It's very annoying!
This scam calls not less than three time a day, 7 days a week, sometimes after 8pm & 9pm. They do not come under the "do not call list" for they are a "profit" non-profit organization.
