Ruby Royal Casino - Want my $2500 withdrawal

I won $2700 at Ruby Royal casino and with draw the weekly limit of $2500, which was suppose to be in my account within 10 business days. After the 10 business days passed, I began emailing them asking where my money was. On the 12th business day I received the an email that stated that I would only receive $300 because I did not deposit enough money and play enough to get the entire $2500 and it would be deposited back into my player account. When I looked in my player account nothing was there. So, I can only receive $300 of the $2700 I won? I did not play after I won the money because I wanted to be sure it was not a scam and I would actually receive the $2500 owed. I would have kept playing if i received the full amount owed to me. I guess I should have looked at the legitimate reviews before signing up with this casino. PLEASE AVOID THEM.
Thank you for an outlet to complain...
