When I sign up, they give me 187 coins free

When I sign up, they give me 187 coins free. Start to play, win money, the time when I wanna pay out, they said I must upgrade to VIP1, it wil cost me R350 and then I can claim my money. After I paid the R350, they said I must upgrade to VIP2, it will cost me another R550, them I can only claim my money
