Well I went to their terms and read regarding the ^{[Promotions and Bonuses]} it seems very risky condition, I think you must read it carefully and understand if you did not violate the rules, but as they have said there.
^{[ 9.5. Rocketpot may amend, reclaim, refuse or cancel any promotion at any time at its own discretion ]}
Let us hope that their team will answer this thread as ^[efialtis] said above, that is a great help to this issue and also may not ruin their reputation since their ANN thread ^[1] was inactive recently.
