I won too much and they became sleazy!

I have been playing at Win Palace for a few years now and they even upgraded me to a VIP some time ago. One of the perks of being a VIP is that you get your withdrawals approved within 3-5 business days (vs 7-10 business days). This has mostly been true in the past. They have been approved in 5 business days. 95% of the time I use a bonus code. I have won some and lost some over the years. Well I made a withdrawal of around 2500 about 2 months ago (and they paid me the entire amount in full) then about a month or so later I made another withdrawal of 2800 asking for the wire transfer option. Well, as soon as I asked for that withdrawal, they immediately cut me off from all bonuses. Fine, not a big deal, I can deal with that. However, instead of my withdrawal taking 3-5 business days, they are now taking their sweet time and going back to the 10 business days (what? I am not a VIP anymore because I have won too much, really?). To make matters worse, when the finally approved it , they only approved $500 and put the rest of the money back into my account. Any time I have withdrawn that kind of money in the past, they always, always paid me the full amount in one payment. Now, they decide because they don't want me playing there anymore (apparently because I have won too much money) they are going to be jerks and only pay me $500 at a time. I spoke to customer service and they said it is in the terms and conditions that they can pay me in 5 installments. I get that, but it seems strange that they decide to do it now. At this rate, it is going to take me about 5 months to get all my winnings. This is so unfair and really, really sleazy. I am so disappointed in Win Palace and they don't have to worry because I will never put another penny in their casino again. I know this is in their terms and conditions but I was hoping there was someone out there that can help me out and have them do the right thing. I would be very weary about playing here. It's fine if you don't win a lot of money and you mostly lose but if you try to withdraw too much they become jerks and cut you off. Please help someone! I don't want to wait 5 months to get my money! Thanks so much for listening. kb
