eBay Inc Stole my money to refund buyer outside policy! Double standards Internet

Buyer purchased a mobility scooter from me on 3/15/2016. On 3/28/2015 the buyer requested to return the item stating that the scooter was unsafe to use as it turned over when being driven up a ramp. We had a technician reach out to the buyer and it was confirmed that the scooter was being used by someone above the weight capacity and the ramp was steeper than was safety tested. The buyer still claimed that the item was damaged. We asked for photos, and all he showed was a photo of a knob that was slightly chipped, which looked like something he damaged on his own.

We offered to replace the part that he was showing as damaged but he refused. He claimed that the scooter was unbalanced, but refused to show photo or video proof. On 4/23/2016 eBay escalated the case and forced me to send a return shipping label at my expense, although it was clear that this was a case of buyer's remorse and misuse of an item. I sent the label on 4/26/2016. eBay policy clearly states that a buyer has 10 days to send back an item from whenever they get the return label. On 5/7/2016, I got an email from eBay letting me know that as the return period expired, this case was now closed and "NO FURTHER ACTION WAS REQUIRED" from me.

The buyer went ahead and sent back the unit, on that same day 5/7/2016, after the case was closed, on the 11th day after he got the label. On 5/28/2016 eBay stole $2049 out of my Paypal account and refunded it to the buyer, even though he returned the unit past the 10 day timeframe. The email they sent me stated that they were waiting for me to refund the buyer, and as I hadn't done it, they forced the refund. That was after I got an email from eBay on 5/7/2016 stating that no further action was required on my part! I called in to eBay and spoke to Holton from the leadership team who was most rude and disrespectful!

He threatened to bang down on me a few times during the conversation, and refused to answer my questions. It is obvious that the 10 day timeframe was missed, as the automated system eBay has in place closed the case on 5/7/2016. The system does not allow cases to be closed until AFTER 10 full days, and closes cases that time out on the 11th day. The eBay reps I spoke to regarding this case could not give me a proper explanation as to why the case would be closed if the timeframe was not up. That is because there is no such thing! The timeframe had expired and therefore the buyer was no longer eligible to send the item back for a refund. Taking money out of my account to refund the buyer is stealing, practicing double standards and completely unethical!
