No one here is able to gain access to their internal system, their wallets, etc. Hence, the only way that you're able to get your money is going to be hoping that support actually helps you with your issue when you contact them.
Keep opening new tickets until you actually get a valid response. Because right now, the main issue is that your withdrawal is stuck in pending mode, and if they operate like any other major exchange, this can be easily fixed by support and their technical staff. If they're not concentrating on the issue at hand, keep bringing them back to the point that you're making.
It is a sticky situation since the wallet is about to get delisted. Hopefully you'll be able to withdraw before that happens, because it may become a lot more complicated once it does get delisted. You do deserve to get it back - it's your money. It's just that CoolCoin doesn't seem to be a well known exchange at all. It doesn't seem to be very transparent or even licensed for that matter. Use a more well known and trusted exchange next time.
