Never received my items and Paypal is not helping!

Description

I purchased an item on facebook through my Paypal on Oct 3, 2020. I then filed a case on Oct 30. and Nov. 17 of the same year because I still haven’t received my items. The only reply I got from Paypal, which i got in Nov.27, is a note with the tracking number and that it was delivered on Oct. 27 in my mail box. I never in the mailbox, and if I didn’t find it I wouldn’t be constantly communicating about it. The items in total cost me $51.97. I tried to communicate with the seller multiple times, but never received a response. I even tried the Post Office and asked who the seller is and from, but never got any information. This is a waste, and this has been frustrating since the start, especially when communicating YOU was the most difficult. Why isn’t there a direct phone number that I could ask call for help to give me assistance? Also, why did Paypal immediately end the case before hearing my side, and why won’t they help finding who this scammy seller is.
