Who can tell?
A transaction has been made to coinlist
Sent BUSD to the wallet ETH, although bsc network is not provided, it was an erroneous translation
How to get your funds back? Is it possible to request a seed phrase or a key from a wallet associated with an account on coinlist?
You have to be very careful with shipping, an error like these can lead to the loss of assets.
But in your case it is recoverable because you mention that it was just a network error. I do not know of an exchange that will give you the phrase or private key. They have their security and one of those is not to give up those keys.
