I received 4 calls from this number in less than an hour.  When I go out, my phone is in my purse in the back seat.  I was driving when the first one came in.  I got to the grocery store I checked the call, number unknown to me I ignored it.  While food shopping same caller twice, last call when I was driving home.  Now I googled the number... other sites list this number as a scammer who can guarantee Social Security Disability Benefits.  Another site said it was about "You Won a Cruise or vacation".  I have had both of these calls before and blocked the number they used last time.  Now their new number is blocked too.
