I live in the University Park Town home association (3rd St NE, Blaine, MN 55434). Last Sunday when I opened my personal mailbox it contained the key for the shared "package mailbox". When I opened the "package mailbox" it was empty. I contacted the Blaine Carrier Annex Post Office via phone 4 times this week to explain this and for any information they could give me about what happened. Each time the person I spoke to took my phone number and indicated I would be contacted via phone after they looked into this further (spoke to the carrier). I did not receive one return phone call. This is by far the worst experience I have ever had with a post office in my life!!!
