as far as i know, if you have gone through the steps and verified your identity, there is no reason for them to hold your money because it is their obligation to allow you to withdraw the money. if they say they need some time to verify your account, that is fine, but when they ask for money so you can withdraw your money, that is unreasonable. i don't know their banking regulations, but at the bank i am currently using they require their customers to deposit money first to use their account, and after that the customer can withdraw all the money. but you already have money in the account and there should be no reason for them to hold the money.

also, i can't access the website, it seems to be an inactive domain.
