I tried to send 50 dollars to the wallet, when I tried to send it back using the same sending address, the dollars disappeared

I discovered today a thing called "arbitrage" which is to send my crypto to a wallet and sell it for a higher price. I just tried to do this a little while ago, I sent 60 dollars to a wallet called "Dexgir" and it hasn't arrived. If anyone knows if it's possible to reverse this, please help me. Unfortunately, this money will be missed, but it seems like a synchronicity of the universe revealing a material detachment. A millionaire mindset and a negative balance, this is bothering me...
