Is this Scam? How can i recover my money back

I have trading at MetaTrader5 (MT5) When I Have total amount of $162,000 plus, I make a request from Rifagala website through the customer service to withdraw my money. After I make a requested to withdraw out my fund from MT5, then only the customer service of Rifa told me that I am not their VIP member, hence I cannot withdraw more than $100,000 from my account. They asked me to pay 30% of the guarantee deposit base on my total fund in the account to secure the transaction. They told me that after I pay 30% of this deposit then only they can release my money to my account. I asked them to cancel my request for withdrawal of more than$100,000 but they said application has been submitted, cannot be cancel. They never informed me got this kind of term & conditions. Feel like a scam. I do not know if I continue put the money into MT5 account, will I get back all my money. Heard that few peoples also face this type of issue.
