When Kucoin has already confirmed that the funds have been released from thier side then you will need to contact ByBit exchange. If they are not helpful or are clueless then you should comeback and update this thread with their reply. This is the first time I have read of such a problem. If you have entered all the details correctly then they will be able to locate the funds credit your exchange wallet.
Bybit has sent me the refund TXID and it is the due of kucoin to the coins back to me. But kucoin is saying that I should pay 40$ which is abnormal.
Actually there's a written information about paying for recovering your funds in kucoin
https://www.kucoin.com/support/8366839950361. I also experience same like case which I deposit my BNB to other chain then the transaction succeed but it never get credited to my wallet since the chain I accidentally used is not yet supported on my personal wallet. When I ask the support for recovery then there's some fees asked maybe for their efforts made. If the amount you lost is huge then I guess paying $40 may have sense at least you can get something from your floating funds. But if the amount is so small then maybe better to move on from this issue then next time be careful on next transaction and make sure that you include the memo or other important requirements so that your transaction will be credited to your wallet. Best to do now is to comeback on their support since they are the one who can help you with your issue.
