Seller threatening me after I received an item different from the description

[d999ma-2]

I purchased an item from a seller from USA who has 100% rating. The listing description stated that the item is brand new, sealed and unused. I received the order almost one month after placing the order. However, when I opened the package there was a damaged postal packing inside the box and the box had no seal. They seemed used and old, with only one earpiece working, other wasn’t working. I checked the serial number on each ear piece and it was different from the one on the box. I reported this to seller and he started threatening me and blaming me that I am lying. He threatened that he will make my life hell, get myself and my family arrested. He threatened he will fly to my place. I talked to the customer agent at ebay over the chat and they told me to wait a few days, if the seller don’t provide return label, ebay will step in. I right away reported the threats and the fraud to my local police. He sent me like 10-15 messages blaming and threatening me. What else should I do?
Will I be able to recover my lost money or am I out of luck?

I don’t want to deal with the seller anymore or reply to him! I just want to throw his garbage stuff and get my money back.

So the seller sent me a fedex ground return label. Should I go ahead and drop the return at fedex or should I confirm with fedex first if the tracking number will provide me updates when the package crosses border and gets delivered? Should I also take pictures of packing back whatever I received? Any other tips I should follow? Many thanks @femmefan1946 @pjcdn2005

It is possible that because the item was handled by the GSP, a less than ethical employee of the Global Shipping Center in Kentucky may have pulled a switcheroo.  If we had known at the beginning that your item had been handled by the GSP our advice may have been a bit different since sellers are relieved of their responsibility for the item's safe delivery once it reaches the Global Shipping Center.

Having said that, your seller's attitude and customer service isn't making them look very good here so I can't 100% entertain the notion that he's got nothing to do with this situation.

The seller's original shipment shows shipping from their location to Kentucky because the Global Shipping Program is a forwarding service.  The seller sent it to Kentucky, other carriers sent it from Kentucky to your location.

If it's likely that loss or damage occurred to the shipment after it reached Kentucky, the GSP is supposed to take responsibility for it.  Unfortunately, it is unclear how the dud merchandise was sent to you.

As far as your concerns about the mailing label are concerned, I don't have enough information to figure out if it would work for a shipment from Canada to the US.  I hope you have an actual FedEx shipping office nearby and not a FedEx agent staffed by non-FedEx employees who may not be very familiar with how this sort of thing works.
