This number called my cell phone.  Did not recognize this number.  Did not answer.  The caller left no message. Tried to call back via a secure line.  The number was "out of service"

Same here

This number called my mobile, the AT&T Call Protect app automatically blocked it.

I too believe this to be a scam as it stated "This is our final call to contact you about you student loan forbearance." I have not had a student loan for many, many, many years.

Also got a call from this number. I didn't answer and they didn't leave a message or call back. Definitely a red flag sign for a SCAM.
