Because platform funds and account entries are managed through the internal wallet system, any reversal or correction is handled in accordance with the account and payment policy.
A deposit or withdrawal request that is still pending has not yet affected your final balance in a way that cannot be corrected. Contact Support if you would like a pending request reviewed or reversed.
If you believe your wallet balance, transaction history, or game history is incorrect because of a bug rather than the normal outcome of play, contact us through the Contact/Support page and describe what you expected to see.
