Grandcapital.net scam

I deposited 500 dollars and won 800 USD. When I wanted to withdraw money, they suggested the lot condition. They said 5 percent lots was a requirement, I made 25 lots, but they said make 9 more lots, I made 15 more lots, this time they used the processing time as an excuse. And they don't return my messages anymore, this company is a fraud, don't jump like a carp!!!!
