Hello, Ill keep this one short

So I sold a small electrical item overseas however the buyer claims not to have received it. (sale was over 2 months ago)!

They launched a Paypal Case and I submitted proof of postage to show that I had sent the item to the specified address. The funds were on hold as the dispute was bieng handled. The case is now closed however the
decision reads:

"After careful consideration, we're unable to decide this claim in your favour at this time"

The money has not been refunded from my account to the buyer by PayPal so I'm just wondering what happened?

Can the buyer appeal the decision? if so, how many times can they appeal?
Is this just them saying that the case is a draw or are they still looking into it?

Any help is appreciated

Many thanks
