Coinbase *****

i joined coinbase a month ago I sent a message on linked to the ceo in regarding problems I am having. Micheal one of the account managers is using anydesk to access my bank account and take funds that he claims he needs to complete my trade. I have been trading with coinbase for the last couple of months and I have made a decent profit but yet to see a cent everytime I try and make a withdrawal Micheal claims I need to pay more for crypto insurance or blockchane parking fees and then he is back in emptying my bank account and it's never ever enough. I have questioned and he get defensive and threatened to cancel the trade and all my money will go to bitcoin miners. So I just bite my teeth and keep quiet. He goes as far as pulling a statement and question me why did a pay out money why didn't i call him I need it to complete my trade. I need your help I believe I am being ****ed I have tried the WhatsApp help line and support email but I get no response just another call from Micheal shouting and swearing at me that I did that. Seems he has blocked me everywhere i try and get help.
