BDG Payment Issue: Deposit Missing

I made a deposit of 20,000 to BDG via their platform, but the amount has still not been received or reflected in my account. The reference number of this transaction is 301816245130, and it has been pending for a long time without any update or result. I have not yet been able to contact customer service about this issue, but I want this problem to be resolved urgently. I request that my 20,000 deposit be reflected correctly and promptly in my account and that I am informed clearly about the status of this transaction.
