I have played quite often at VIP Lounge and I am very surprised by your post.
I never had any problems with them and my wins were paid without any fuss.
In my experience, the way it works there is that there is one general set of rules for reloads. It's on their website here :

I have always assumed that, unless otherwise specified, those are the rules that apply and it worked out fine for me.
If this Thanksgiving promotion was an email offer and there were no specific terms mentioned, you have a very legitimate grudge.
