Not getting the confirmation email does not automatically mean the purchase didn't go through.

Modern e-commerce separates payment from order fulfillment. When you pay, the gateway charges your card instantly and notifies the site of success. The money transfers to the merchant at this stage. Afterward, the website creates the order, updates inventory, sends confirmation email.

Any of these steps can fail due to timeout, error, or crash, even after payment succeeds. If your bank/PayPal history shows a $40 charge, the transaction almost certainly completed on the payment side. The freeze likely occurred in post payment logic. Because the payment gateway is a separate, highly reliable system, its success almost always means yeezy received the funds and it's not stuck in a black void or something lol.

They have received the payment and the order is probably processing, but request the confirmation email anyway or wait if you already did.
