This assumes that you're the type of person to do that. A lot of people said when they put a job profile online, they started getting these calls. It was the same for me. I started getting calls from this number and others after I put my phone number in a job search profile.
When you fill out surveys to get a "free" $1000,00 Visa card on-line they sell the information you give them. There is no such thing as "free". Don't fill out any surveys and these idiots can not sell your phone number or email address.
