"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.
I received a call to my cell phone number. The recorded message was about reducing my student loan payment. I have no student loans. All were paid off over 40 years ago. I called the number back...surprise...caller not available! SCAM!!!!!!!!!
