Me too...I made the mistake of filling out a form that was online under the banner of my college....only to find out later that it was not the school...but a marketing company charging for their "services"!! Beware out there!!
Received calls from this number in times past and never answered or added to my blocked callers list, and looked it up on here to see what it is/was. They left no message, and while I do have a LinkedIn profile, I didn't sign up for, or include anything under my education recently, so I'm not so sure this bogus telemarketing thing is LinkedIn related. -My two cents....
