I've received a couple of calls from this number, 786-607-1799, on my cell phone recently. This number is familiar to me and from research on Google, this is a scam call.
Called them back with a blocked number and a recorded message said "Hi, this is Julie from Rewards Redemption. You recently visited one of our websites and to show our appreciation we want to give you a gift card to Best Buy..."...after which I hung up. I'm on the DNC list. Reported and Blocked this spam caller.
