I got a call from this company as well. I have a son that is going to be a senior in high school next year and wondering if they got our phone number from a college information fair that my son attended. It was a place where several colleges had information available, but also wondering if there is a database related to that somewhere.
Just got a call from this number. Didn't answer because I didn't know who it was. Already blocked it. To block depends on your phone. If you don't know how you should probably check the instruction manual. On mine I just hit 2 buttons but I think some are more complicated.
