Figured it was a scam but answered because area code is same as a friend's so did without thinking. Person sounded almost like a computer saying "I understand you are interested in furthering yoru education." I proceded to spell out the 3 degree I possess and he sounded duly impressed, I then told him it was a cell phone and to put my name on the "do not call" list and not to call again - I figured he had my number since he'd called. We'll see if they try back, I hope not but at least now I recognize it. (Not sure how to block numbers on my plan.)
Got two calls from them today on my cell phone. Hung up on both times. When I got home I called on home line, they said I had filled for school classes. Told them I was 67 and already had my college degree and I don't need any more and hung up on them. The way I see it, God has a special place in HELL for these scamers!!
