Poloniex Exchange Has Not Fulfilled Withdrawal Requests For Months

My XLM withdrawal request has not been realized for months, and I cannot find a contact person; I wrote from everywhere. They responded as if they were making fun of me and blocked me from their Telegram channel. They closed withdrawals. My pending transaction timed out, and my funds were lost; Currently, it neither appears in my Poloniex account nor in the wallet I want to withdraw from. Do not trust this exchange and do not lose your assets. They are punishing us for their own mistakes. I hope justice will be served in the face of injustice.
