Always have been treated very well in person since I have just moved here Oct 2023. I have a question about small packages that do NOT fit into my group mail box because I live next to the Foxhole. My apartment address 1300 N Riverside 2D faces the Fox River only 50ft away. Yet whenever I order a deliver People cannot find my front door. So I looked myself up on Maps and you’ll see it has a picture taken on Riverside Street showing the Red Brick Hotel building. That’s why People can’t find me. Picture taken as if you are standing on the Bakery side or West side of the street looking East. If looking through the Big Parking lot you can only see the Back of my building which does not have a back door only a front door. If you can help me get the right picture of my front door that would be great I can take a picture like from the 120 Bridge showing the 18 units where I live. Thank you Michale

I dropped 2 boxes into the parcel bin, after using the lobby purchasing machine One has the address/ tracking number etc. The other is missing the label and postage label. I forgot to apply the label. The box measures 17"x 13"x 11". The box is light brown with Green writing and symbols on the box .I used beige mailing Tape.and there is a handwritten K on the top of the box made with a black inked sharpie. Can I get that box back so I can apply the mailing label, Please....... Nancy Miller
