Rude staff, my mail box was full so they take it back, the mail carrier left me a sticky note without date or more info other than box full. I asked her where to get it and she gave me this location address so I stopped by today and they said don't have anything to wait at home they might return it back, and I said well the mail carrier told me that's not an option, then the office guy told me then dont complained is your fault why let it full... yes I know is my fault but he doesn't know if I was dying in the hospital. And since then 9/12 they haven't delivered any mail to my house.. I called like 20 times to the postal service manager and they don't answer is just a voice message operator with a few steps to do but nothing related to my issue...
