"Hello, this is Sandra from the National Student Aid Center offering you a chance to save 40% on your student loan payments." Gee thanks, since I've never had a student loan. Robocall, obviously a scam.
The number came up and i didn't recognize it. So I googled it and got the complaints. I have added this number to my 165 numbers that I have googled and found out they are all scam calls.
