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.
The fee is madness to be honest since the funds return to the exchange hot wallet. You the TXID so the support only needs to do is to credit the amount back to your account.
But that 40$ is the only answer to solve your issue since the funds is already back on Kucoin while they have policy like that. Also there’s a mistake on your side here so you have no choice even the if amount of fee is high.
I believe even the cs on the forum can’t do anything with that fee since exchange charge it for inconvenience.
