Dear x_toval,
You have to give 7 days to the Buyer after he has committed by buy.
After 7 days you can file UPI.
Then, if there is no response from the Buyer for 10 days after filing the UPI.... you can request for FVF credit.
eBay will generally apply credits to your account within 7-10 business days.
It will show in your Seller's Account.
