this number and 6572026719 have called me multiple times. i finally answered today and it said, "Hello, ive been trying to reach you about getting out of credit card debt." at which time, i promply hung up.
Just don't answer it. Add it to your phone list (if they're calling a cell phone) and just have them go directly to voicemail. If not you can contact your telephone company and have a block put on that number if they don't stop.
