Lost Over $1500 Due to Delisted Coins on MEXC Exchange

I recently purchased around 8 different coins on the MEXC exchange, and now they have all been delisted. I’m facing losses exceeding $1500. If these coins were going to be delisted, why were they listed in the first place? Who is going to cover these losses?

For example, the OST token is still available on other exchanges and hasn't dropped significantly, yet MEXC delisted it at a value of 17.0. What will happen to the tokens I still hold? Who will compensate us for our losses?

I need answers and assistance in resolving this issue, as the current situation is causing significant financial distress.
