eBay

Need some help guys so I made a sale on eBay after I had already sold my item on a different site (I forgot to take down my listing ) so I gave the guy a refund it says I’m negative that amount of money on my eBay and say his money is still on hold. ...

so I sold an item on eBay but didn’t ship it yet and my money is on hold I sent a refund back to the guy and I accidentally marked it as shipped so not sure what I’m supposed to do here it says available negative amount of money I really messed up he...
