Just got a call from Linda who was our former carrier on Nicola Rd Middleton. We moved last month and she got a few pieces of mail for us- not only did she notify us but she offered to do the forwarding form for us! What a refreshing person to have at USPS !! Patty Ramsden

We have lived in Middleton for the past year and had multiple issues with our mail. They range from boxes and products being shoved into our mailbox that clearly don't fit, leading to us having to force the damaged products out of a box it should have never been shoved into in the first place. Our latest issue has included our mailbox being knocked over and broken by the plow truck and the following day our mail being left in the snowbank rather than near our door or left at the post office for us to pick up. Again, things we pay for are being damaged due to carelessness and complete disregard.
