USPS marked my order as delivered yesterday, 11/18/2022 but I have not received anything. After calling them, I confirmed with them that my address was correct. After that they said "We'll look into it" and I haven't received any contact since. I am aware the fault belongs to USPS but I would like to know what I could do in this situation. I am extremely distressed about this since I waited almost 6 months and USPS decided to do this to me. Any help would be appreciated.
Order number: US16536H
