Two calls received within an hour on 7/14/2016 - No message left, but on the 2nd call, I could clearly hear the sounds of a boiler room/telemarketing operation. The caller said, "Hello..." but then hung up.
Caller claimed to be Hilton Grand Vacations. Offers were too good to be true. When I started questioning his affiliation to Hilton Grand Vacations, he hung up.
