I have NEVER had any problems with package delivery until recently. I assume we have a new delivery person. My packages have always been placed on my front porch until recently. I received a re-delivery notice in my postal box (neighborhood delivery group boxes) saying I was not available to receive a package????? The package would not have fit in my box. There was no information on the slip except the date. Why did the postal person not leave the package on my front porch??? I would say because he is LAZY. I want my last postal delivery person back. What is going on with the US Postal Service????


I don’t know what happened but they have left the complete back of our road box completely open. It was locked but it was wide open on ballot delivery day. I was able too force it closed!
