I think it is from a telemarketing company. It is from a dating site trying to get you to inside. You leave a message thinking it is real and then go into the site. They also get a contact number associated with your email. Could be ID Theft initial launch. the sites ask for a cc to verify your age. Also contact info ect...
Just a personal opinion but I am Criminal Justice major.
I actually was stupid enough to call the number. What do I do about it now? I didn't use my credit card on the site, thank god since I was fooled before. So what about the call and message I made?
