Poor service

I played slots yesterday I won 2thousands and something immediately when I tried to withdraw my win my balance showed 2hundred and something n I went back to the game the 2thousands was still reflecting but when I want to withdraw it say 2hundred I continued playing n won 6thousands something but when I want to withdraw the balance was hundred n I went back to the to check it was 6thousands then after few seconds the page disappeared. I quickly lodged a query online n I was told I ddnt win I so disappointed to a point of closing my account because hollywood ****med me my winnings.
