HELP ASAP

Help…

Here's what happened. At about 11:23, I decided to place a limit order to buy 5.3 ETH for $2,204 each. At 11:24, I received a message saying my 5.3 ETH was filled at $2,204. So, I decided to check my account, and realized that my portfolio only says 4.3 ethereum instead of 5.3 ethereum. I'm not a noobie robinhood user, so I know how partial orders/filled orders work. As a logical person, I tried checking if my order was partially filled but no, it was fully filled and I lost ~2K in a matter of seconds. I tried redownloading Robinhood and logging out, nothing changed.

I need help.
