OP
Would you mind sharing your last deposit transaction? It might be possible to see if KuCoin still holds any of this token, or when they got rid of it, anyway.
I've used KuCoin pretty successfully over the last 3-4 years, never had any issues with them.
I'm surprised they're not more willing to work with you.
It shows on etherscan with the txhash 0xd16772113691bd3b14efbd8e93818fd07fcba42285151706ce55e4b94f067256
Alrighty. I'm a bit busy at the moment but sometimes Ethescan identifies wallet as "KuCoin 1" or something like that... it would be interesting to see if they hold any of the token you mentioned. I'll give it a look in a few hours, but you should take a look for yourself in the meanwhile, see if you can make sense of it.
