I sent .0386 bitcoin from my wallet and the receiver said they only received .0000386 bitcoin my history shows that I sent .0386 bitcoin
did I get ripped off? What recourse do I have to recover?
You alone can identify if you are ripped off or not. As Ognasty said, show the TXID so we can see and verify if you sent the right amount. There's no way to recover those sent bitcoins, you should know that bitcoin transactions are irreversible. Once it is sent, you can't undo it. I guess the receiver is just trolling you around or he/she has a blurry eyes.
