Re: KuCoin is freezing my funds and not providing adequate customer supporr
Update: My funds are still stuck 
Any chance your funds are come from high risk sources? AFAIK Kucoin has been partnered with chainalysis, chainalysis is a company that tracking cryptocurrency sources and would know the sources came from. Quote from: https://m.kucoin.com/news/en-terms-of-use
Further, pursuant to the AML/CFT Policy, KuCoin may, in its discretion, carry out continuous monitoring of all KuCoin Accounts. If any unusually large or unusual patterns of trades or any inexplicable or suspicious circumstances are observed, KuCoin may, in its discretion, place an administrative hold on or freeze your KuCoin Account.
Have you contact him in this forum as @noorman0 suggested above? I think it's the better solution to reach KuCoin support, I saw he respond the other who has an issue.
