Unable to withdraw and disabled my account

I tried to withdraw for the first time after I made good profits. Then I waited for one week but no action taken, then I messaged them via a messaging tool on Garsons website. So they asked me to pay1% commission fee to a third party. I did not want to argue so after I paid the 1% I was asked to wait for another 3 days so I waited then nothing happened. So I messaged them again but this time they said that I have to pay 2000 US dollars as a management and maintenance fee for the mt5 platform
