Call their hosting service godaddy and tell them you would like to report them calling your phone with a robot dialer. Enough calls and reports and they should be forced to stop. They have private registration for goldenticket411 com but going straight to godaddy and explaining they are using their service for spam is worthwhile.
Didn't answer. I get calls all day long on my cell phone from the bad type of telemarketers ... robocalls that when you dial the number back it won't go through. I'm getting really sick of it. Judging by this site I'm glad I didn't answer this call.
