Funds still on hold after phone rep closed return case
Title
I had sent the wrong item to a buyer, and after being notified, sent them the replacement item the next business day. I let them know about the replacement, provided tracking, directly in ebay private messages. I apologized and gave them a partial refund for having to wait about another week.
Despite my doing so, they still opened a return case against me, 3 or so days after I had sent the item out. I sent my buyer a message telling them they didn't need to return the incorrect item and they could keep it (I sold a Yugioh card and the incorrect item I sent was a card that was related to the deck the original item usually plays). I tried to get them to close the return case by once again notifying them of the replacement tracking and giving yet another partial refund in the return stuff, but they denied that attempt.
To me, this means they've seen my messages and are just ignoring me? They had to have seen the information when I included it in my attempt to close the return case, right?
I don't know what's going on. I've called ebay twice, and both times, the phone reps told me the case would be closed in my favor since I had sent the replacement out immediately. Both reps told me they closed the case, but my funds are still being withheld even after their 24-48 hour wait time. When the return reaches me, is my buyer just going to be refunded? They're just going to get the item for free?
