You thread has a lot of unnecessary that makes your main goal not clear here. What exactly do you want to achieve on this thread because you clearly admit that you give a negative review against Duelbits which is why the support contact you. I don’t see on the proof about the promised reward but rather just a regular statement of offering you bonus once there is available and not a specific bonus tailored for you.
Proof and Evidence:To back up my claims, I've attached screenshots of my transaction history and email conversations with Duelbits' support.

How come this is an evidence to backup your claim. You play different games which means you have different rakeback to get due to house edge discrepancy. Also Duelbits bonus consist of "others" category that means of different bonus that you join. The bonus amount of other user even though he has lesser wager volume than you means you should get higher rewards. It still depends on the game you are playing and the bonus both of you avail.
