USPS emailed me that a package had been delivered to my centralized mailbox in my neighborhood; the package was not there. I went to Highland post office the next day to let them know that the package was probably put in someone elses box (as this has happened to me before); the internet was out so the office was not open just a sign saying to go to other branches. I went to the post office on Hackberry and the manager there, Duncan, assisted me. He listened to me, took the tracking number and sent it to someone from the Highland office to make sure the carrier was notified to correct the situation. Duncan took the time to assist me with a problem that was not related to his branch. The package did show up later that day at our mailbox. So thank you Duncan for your help, more employees need to follow his example. It just took time and the willingness to help the customer.
