What is the refund for?
If you have returned an item through an Ebay case, then the seller has 48 hours after the tracking shows the item has been delivered to them to refund you.
If they don't, then you go back to the case and ask Ebay to step in.
All refunds are processed through Ebay.
The refund will be sent back to your original payment source.
When a seller instigates a refund, Ebay will send you an email to say the refund is on its way.
So, have you got an open return case with Ebay?
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
