You know I've been calling for days and no one will answer the phone. They have no working local phone. No one answers when you dial their local phone number 623-434-3580, they have no listed Messenger way to contact them, and no listed email. Sierra Adobe is unreachable. I think something bad happened and maybe all of the employees over there were killed or something. That sounds extreme but what is going on? Why is the post office unreachable??

Its such a bad neighborhood that they lock the parcel drop next to the self service kiosk. Whats the point of having it always available if u have to take your package back home with you anyway? Horrible hours all around

My pink slip said I could pickup at 9am on a Saturday. This website says I can pickup at 9. However, the employees here did not receive the memo. I was told to come back at 10 by 2 employees. Get it straight!!
