Morris National Asset Recovery Service Man called with South African" accent telling me I had won money and a car. Las Vegas, Nevada

I received a call on my cell phone from "Morris National Asset Recovery Service" stating that I had won a large sum of money and use of a car for a year. I was asked to call 702-421-9505 to verify my winnings. I tried to look up the company and found the number was from Las Vegas, NV area. I called the above number and the person who answered was hard to understand and was "verifying" that I had won. In the background I heard noises like a telephone call center. Since they were so disorganized, I deemed them to be a scam and hung up. Since then I found numerous reports for "National Asset Recovery Service" and filed this report.
