just got a call from this number. Said his name is special agent Mark Waller with the DEA in Los Angeles. Its a scam. Don't listen to them. Just ignore them. Hang up and report them to your DEA office.
Same thing - multiple calls threatening arrest if not given $1200 in Green dot money cards w/in the hour. Also "Special DEA Agent Mark Waller". Reported do DEA at 877-792-2873 fraud extortion dept. If you get one of these calls please report it. I also notified my local police dept. and the DEA in my state located in Salt Lake City. Maybe they can catch these scammers if enough people report them to DEA.
