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.
Scam call from foreigners with recorded message, "Hi, this is Julie from Rewards Redemption. You recently visited one of our websites ...". Pressed 1 to talk to the scammers to waste their time. These retards do not have their phone PBX set up correctly to option 1 forwards to a non-working number.
This number just called my pay as you go cell phone and only let phone ring one time before ending call. Phone rang at 3:34 PM on 7/6/2016. Never call this kind of call back! The crooks behind this scam will then say you called them and your phone will never stop ringing with many scam calls!
