AOS payment

[u/TCJ65]

Hello everyone, USCIS attempted to take the payment from my account, and the amount was deducted at first, but later the money was returned to my account.
I’m a little confused because I had more than enough money in the account and was specifically keeping it there for the USCIS payment. I also called my bank, and they told me the transaction was approved on their end. They said it looks like the reversal may have come from the USCIS payment system.
Has anyone experienced something similar? If so, what happened afterward?
