Mason PO - frustrating. I call and am placed on hold. After 5 minutes I hang up, call again and it rings for at least 3 minutes. Then, I'm disconnected. Great servcie. :-(


Kaleb? Caleb?.... Yeah... He's works @ 45040 PO & is basically the bomb. Super nice. Super friendly & I'm wicked high maintenance and he pulled thru w a smile lol THANKS! Always love this place <3


I am usually happy with my mail service, but in the last 2 weeks I'm finding the door to the mailbox open and rain soaked the letters. Yesterday the box door was open and 2 letters were laying on the street. No reason not to shut the doors on the mailbox and ensure you are putting mail into the box. Seems someone is moving fast and figures moving fast is better then doing the job correctly in delivery to the mailbox and shutting mailbox door to prevent making it easy for someone walking by to see or grab mail, or due to inclement weather, damage to mail.
