BUSD (BEP20) to USDT (ERC20)

Hi ,

I have sent USDT from Metamask (BSC) to a custidial exchange (Change Invest) they use ERC20 network by mistake and of course , funds did not get there.
I have contacted change invest and they are sending me to contact Binance… because its their Network… of course Binance sent me to Metamask and here i am … i already sent a ticket to support and see what they can do but it seems that i have lost all my funds right?

Any help?
Appreciate it.
