Case closed, refund not showing on my Paypal activity

[ffebf]

Dear PayPal community, 

I sold an item on Facebook Marketplace and the buyer insisted on Paypal payment. I agreed and she paid for it but I then got a weird feeling about her and thought she might be trying to scam me (pick up the item and claim she never received it etc.). I politely let her know the very next morning that I can't accept PayPal as a payment method and issued her a full refund straight away. She never replied after that, so I sold the item to another buyer.
5 days later I got a bunch of Paypal emails in the middle of my working day. Apparently she filed a claim and Paypal decided and closed it within just a few minutes. I got an email saying the case was closed in my favour and they issued a refund to her as per my request. 
I thought that was fine as it's what I wanted. The last thing on my mind was to keep anybody's money. Later that day I had a chance to look at my Paypal balance more closely and it said her refund had been canceled (was previously pending for 5 days). Now, I did not cancel that on purpose but rather googled that I must not have had enough money in my PayPal balance. I never issued a refund to anyone before and thought it would go through immediately or be charged to my credit card but apparently it didn't. The buyer filed her claim so quickly that she didn't give me a chance to reply, apologise, or send it again. (All I got was a nasty email from her after the case was closed)
Now what confuses me is that PayPal closed the case saying "As requested, we have issued a refund of X to X and this case has been closed". Yet I did not see any new refund on my Paypal activity. All I could see is the canceled one. I issued a new one myself, because I obviously want her to get her money back and not keep anything that isn't mine. However I am afraid now Paypal might issue the same refund a second time as per their email? Is it possible she would get a refund more than once?

Thank you!

You issued a refund through the original transaction I presume so it would go back to her original payment method so she has to check her payment method. If it's a bank payment, it would take a handful of days, if she paid with card, it can take a week, up to 30 days for the card is post the refund in her card account. When she filed a dispute, PayPal probably saw that she was already refunded, that is why they ruled in your favor. After that I have no idea what happened. lol
