Refunded Buyer and Ebay withdrew the same amount again from Paypal

[johnnyshop-0]

I had a buyer purchase a pre order item.  The buyer then decided they did not want to wait.  They sent a question, opened a case and asked for a refund.  I was professional and answered their question and said I would be glad to offer a refund.  I chose that option on the buyers dispute and thought it was done.  The refund for $285 proccessed out of my paypal account on May 11th.  On may 17th the case closed and then ebay also pulled another $285 out of my account.  I reached out to PayPal and they said I needed to contact ebay about their charge of $285 and I called them this morning.  I sat on hold for 66 minutes before I gave up and came here.  Any Ideas?
