This is the most frequently mistake that people made in crypto transaction. I have joined an icon project as a customer support and find that so many people lost their funds by sending wrong stable coin (usdt, usdc, tusd). And also, people are lost their funds because they sent their coin with wrong network especially when transferring funds from binance. Instead of sending usdc with erc20 network, they're sent with bep20 network because they see it has lower transaction fee.

The only to get your funds back just by contacting the support of that exchange. If they ask you wait, then wait. If you wait for too long, spam in their telegram group with your case to get an attention (well I don't really recommend this).
