I used a no deposit coupon at windows casino I finished all playthrough requirement with balance of 20$. I talked with supported staff online and was confirmed that I am fine to cash out this money. However, they asked me to deposit money before I cashed in. I therefore made a deposit at windows casino. I play some slot games and then I try to cash out the whole money from them. I expected my money could come back to my account some days later. However, the 7 days later, I am shocked that they locked my account without any notice! The reason is I was not entitled to use that coupon To my understand, the system will not work at all if the player redeem an expired or invalid coupon in RGT casino. They returned my deposit (no winning) to me in an hour after I wrote a complaint email to them. They did not response my email any more now. That is my recent experience at a BEST ONLINE CASINO, WINNER OF 5 ONLINE GAMING AWARDS 2004: windows casino.
