Hey OP, you can take screenshots of your conversation with customer support and upload them to any image hosting service then post the links here.
I had to read the copy-pasted conversation and here is where I stopped and I think this is the most important part:
12:01 AM | Sheque: well that seems like a smart idea, and i would like the actual calculations... because 40 dollar for a 350 loss and 30000 wagered is absolutely disgustingly low
Casinos do not give you a reward (daily/weekly/monthly cashback) based on how much you've wagered. They give you a small percentage of how much you have lost. Otherwise, mist of them would have shut down their doors by now.
You have lost $350 and they gave you $40 back (plus few bucks as a weekly + monthly bonus). Sorry, but what did you expect more!
