This post office has lost and stolen multiple of my packages and have refused to help me when I have complained. I have lost hundreds of dollars because of their poor service and assistance. Honestly the Sunnyside Post office is the worst post office in Denver and their service is terrible. I am beyond angry as I have lost multiple things due to their ineptness

Should probably change your hours if you don't actually open until 9 am.
