eBay

how can I go back and see all of my unsold items for the last 3 months?

I just received a message that a buyer did not receive her items that were shipped on August 12th, 2018. I do not know how to find out why they went to another person. I have all the tracking info and it went to a distribution center and the address ...

Tracking shows that her package was delievered to her house. She opened a case against me because she claims she never received it. What do I do now.
