bad service

I went to carnival city casino on the 23/07/15 around 16:00. I played machines and tables untill I lost all my money. I noticed that I had point in my card that I can exchange for cash or free play. I asked one attandant to assist. When he failed he asked me to go to mvg desk for help. I went there and I was sent from pillar to post. I got ****ed off and left. My card number is ***.
