Also received a phone call from this number.  The caller did not leave a message and I have no idea who it would be.

rewards number telemarketing from internet

I don't even live in Metro-Boston anymore but New York.  Called the number back and it was an automated recording saying they got my number off the internet and were offering rewards to stores in my "area", which was Boston I assume..

I answered on the first ring and was abruptly hung up on!
