PayPal G&S dispute escalated – typical refund timeline?

I recently escalated a PayPal dispute and wanted to ask about the typical timeline.

This was a PayPal Goods & Services transaction for $175. The seller never provided any tracking number or proof of shipment, and the item was never sent.

In later communication, the seller admitted that the situation involved fraud. Shortly after that, the Reddit account used to contact me was deleted, and the email address used for the transaction also appears to have been deactivated.

I’ve already escalated the case to PayPal. For people who have gone through similar situations, how long did it usually take for PayPal to review the case and issue a refund after escalation?

Thanks in advance.
