Answered  (as I was expecting a call from an unknown number) and was offered a recorded deal for student loans ,or some such crap ( I'm 67 , and  have 4 years of college eligibility left ! ) . I listened and was given an option to press 5 to decline the offer , after which, the announcement said I was placed on their D N C list . We'll see !

Unknown number calling my cell phone.  I did not answer and they left no message on V/M.

Called my mobile number while I was at work. Did not leave a message.
