@meanuuu First of all, we are here to help out members who need help, freely and willingly, so there's no need to offer any reward incentives please.
Secondly, your deposit/s may have been stolen or rerouted elsewhere by hackers (usually deposits in crypto currencies), so we need to know by which method you had used.
Thirdly, the casino may not have received your deposit/s due to some unseen technical glitches or loopholes, which again my have been caused on purpose by capable people.
Fourthly, it must be a considerable amount of money that you had deposited, or elsewhere this 'disappearance' shouldn't have happened at all.
There have been reported cases whereby deposits were not received by the casino due to technicalities issues, but were later on credited into the accounts once the issues were resolved.
So you really need to let us know what and how your deposit/s went into limbo, or disappeared before we can give further advices.
