I am being scammed by the Grand Signal Market platform where I deposited my money because they are making it difficult to withdraw my money. When I asked for a refund of 4150 dollars, they demanded to pay 622 dollars in taxes 15% in favor of the Central Bank of Saudi Arabia, then after that they asked to pay 290 dollars, a difference of 7%, then for the third time they demand to pay 830 dollars, 20% cybercrime insurance Please Help me
