Unfortunately, nothing we can do about it here on bitcointalk as KuCoin doesn't have an official thread here so we can't even try t press them via negative feedback.
Kucoin don't have an official representative here on the forum so there is no need to share the ticked number.
They do have it
[ANN] [EXCHANGE] KuCoin Exchange Thank you Jawhead for correcting me. I didn't know they have an announcement thread on bitcointalk, maybe because I rarely visit the altcoins board. My bad!
Yes, posting in their Ann thread or sending them a PM seems like the best way to get a quick response. However, OP's case is a bit different than the case you linked because he claims he KYCed his account and sent them all necessary documents. He also said that withdrawals were disabled since last August. I hope it will be resolved the same way, though.
