Black Lotus Casino - Stalling deposits refund

Recently i made a deposit of $900 using my visa card in black lotus casino without any bonus. I made a $500 profit and request my cheque for $1400. I submitted by documents and did not hear anything from them even after one week from my withdrawal request.

When i called their customer service they said that i have dispute with one of their sister casinos. (Yes i did dispute with one of their casinos earlier for $100 due confusion with merchant name in my credit card statement) Later i tried to resolve that but they did not take $100 back and closed my account.

My concern is they should have not allowed to make me to deposit my money in their casino if they had some problem with me. They took my deposits and told below points.

I am not eligible to take a single dollar profit from what i earned fair and square (I had a long discussion with them about their terms and decided to leave my profits) and close my account with them.

They said my original deposits will be credited back to my card in 3 to 5 business days. Its almost ten business days and is still do not see a penny credited to my account. Who can help me to get my original deposits back. Every time i call them they repeat same thing that it will be refunded.
