I hope this is the start of you getting access to your account. Once you have that access, withdraw all your funds from there and move them to a non-custodial wallet. If you are still actively trading until now, look for the most trusted platforms. Poloniex isn't one of them anymore.
Imagine keeping your funds for many years there. Everything could have gone wrong and all your sacrifices go to waste. Perhaps you started using Poloniex back when it was one of the most trusted. I, too, was a Poloniex user way back in 2016-2017. From the top, Poloniex has since hit the bottom.
If you're using Poloniex from a restricted country, I wonder how you would pass KYC but I wish you all the best. Again, once you can withdraw your funds, do it right away. And learn lessons. Keep only your trading funds on a trading platform. The rest, keep them cold.
Please keep us updated.
