Dodging payment of legit winnings

Beginning first week of Nov.2014 I deposited and played at Win Palace. Got my balance up to $500. On 11/09 I requested $500 withdraw. On 11/20 Was Approved for $500. On 11/23 I Deposit an play again. I won$1000. I requested $1000 Withdraw. on 11/24 Iwas Supposed to receive first $500 And Did Not. I Wait patiently. on 12/08 I contact casino payment processor and inform that I haven't received funds. They respond with "somebody made a mistake and sent money to wrong place". on 12/04 Casino approves 500 of the 1000 request. I ask why only half and am told t&c says they may break it into payments. REALLY? OK whatever. Im Instructed to make another request for the remaining 500 and I do on 12/04. meanwhile on 12/12 im Supposed to receive 500 from the 1000 and don't, now im missing two $500 payments. On 12/15 I email casino about not receiving two $500 payments. payment processor called me and said I would definitely have funds in my account by end of business on 12/16. didn't happen. On 12/17 I receive email from casino stating that they denied the second $500 From the $1000 Win. put my account under review for up to 90 days. Absolutely no reason for this other than avoiding payment. how can they approve half of wins and deny other half? Very bad practice in my opinion. Long story short, WIN PALACE owes me $1500 that I won fair and square. in reviewing my deposits it isn't even a win. I Didn't use any bonus on any of this either so they cant say I broke some stupid rule. it was all luck and knowing when to stop. Please Help. I Can provide all email documents to support this claim.
