treneleg11 Item Ordered on Ebay

I ordered an item that they were selling on ebay.  I frequently order on ebay and haven't had a problem receiveing my items that I purchase.  However, this particular item I never received and the seller treneleg11 company based in China says that I did.  I am not a person to make up a lie that I did not receive an item when I do  receive the item and in this case, I did not. 

I also contacted the local post office and they told me they didn't want anything more to do with this issue and that the item was supposedly delivered on March 5, 2022.  It was not delivered at all.  I am very upset with the seller on ebay and the local post office.  I am not one to make things up.  Very dissappointed on this ebay transaction. 

Even though it is not a lot of money, $8.88, I'm still out the money on an item I never received and they said that the case is closed and I won't be receiving a refund.  Why are they choosing to be so mean to me?  I didn't do anything except buy an item on ebay that I never received.
