Welcome to the MetaMask Community @Longtran1412!! 
When you say your wallet was “deducted the 80 USD” was that the token amount you sent or the gas fee cost? You should receive back the tokens you sent, but the gas fee will still be taken.
The gas fee is determined and taken by the network, not MetaMask. The fee fluctuates based on demand for transactions to be completed.
