Yeah I uploaded it to the case and the action bar still says "awaiting delivery" though when it shows the tracking information it shows clearly that it has been delivered on the case page.

The fact that he sent a message asking if it had been delivered makes me feel like he's going to delay this as much as he can, even though the case states I would receive the full refund as soon as it shows it has been delivered. 

Is it something that ebay refunds me or is it the seller that has to do the refund?
