Who called from 2535079833

Received a call from this number but did not answer.

this caller (a recording) said I won a vacation.  Asked if I would answer a few questions.  Paused for me to say yes, when I didn't say anything asked if I was at least 28 years old.  This is a scam.  There is no way to ask to be taken off the call list.

See this number regularly on my caller ID, no message ever left and I will never answer calls from unknown numbers.
