Refund from SHEIN via Afterpay – money taken out of my account instead?

I placed an order on SHEIN but decided I wanted to change the sizes, so I contacted them. They said they couldn’t change the sizes and advised me to cancel the order and place a new one. I went ahead and cancelled the order and processed the refund.

I got confirmation from both SHEIN and Afterpay that the refund was successful and that it would take up to 10 days. At the time, my bank showed the refund as “pending,” so I figured all was good.

But today, I checked my account again and noticed that the money has actually been taken out of my bank, which makes no sense, shouldn’t it still show as pending if it’s a refund?

I called my bank, and they told me they’re not holding any funds and that I should follow up with Afterpay. I reached out to Afterpay, but they haven’t been very helpful.

Has anyone else had this happen? How long does it usually take for a refund like this to fully go through? I really need the funds back before I can place my new order.
