The ebay team told me many times that I have made attempts to solve the issue and they are going to ask buyer to send the item back and be refunded. Buyers refused to do so as it was not his intention from beginning.

While so was waiting for eBay team to find a solution for this problem, they went ahead and fully refunded the buyer and left me with financial loss.

like a deaf person, eBay team members that I don’t talk to ( email or chat) keep telling me to send a label. No understanding of the US costumes laws. 
Buyer has refused to accept payment by seller and purchase a return label  himself, as he is the only person that can get permission from the costumes and sign the label.

This means that eBay has no respect for the seller rights. 
I have lost my microscope worth more than 1800 AUD, have paid for postage and also insurance for postage and on top of that 15% of my microscope’s price to eBay.

Buyer has received a microscope for free. That is unbelievable.

Horrible service by eBay.

This transaction is illegal and scammed.
