I can not withdraw, and money was not received after application approved

The first 3-4 withdrawals, the broker still allowed withdrawals right away after i apply. But those next times the broker suspended the withdrawal order. They let my withdraw application still in pending status for weeks, and not gonna to approved. I had 5000 USD deposit here, the 2 latest application before the last one have been approved 1700 USD + 689 USD, but i did receive any money. My trade order also have been disabled. THIS IS SCAM BROKER FOR SURE.
