I'm not sure if this is a bug because twice making deposits I get the same problem “balance not credited” they just refund the balance without explaining why each deposit is not credited... it's a bit confusing.
I sent an email to
support@betpanda.io explaining the chronology of my deposits not being credited... then I got this reply, obviously a dissatisfied reply, like they don't know the meaning of this issue.

Based on that email it seems they don't have plan to disclosed what the issue is, but I believe for me, it's just a bug, which is pretty common to any platform.
There's nothing we can do but to respect what they said.
I know for a fact that some platforms like Binance exchange don't like funds from m*xers and maybe this could be the reason behind this..maybe source of funds is coming from a place the casino deems questionable **just my guess** perhaps trying changing wallets when trying to fund your account, hope this works and goodluck.
I don't think so. Even if I think the funds came from the flagged addresses(with illegal history, m*xers, or blocklisted), I think it should be credited, but the account would be frozen, and the casino would demand some documents.
But the issue is it wasn't credited the common cause is usually on their backend related to payment gateway.
