All my bills that were put in the mailbox at Dorrance and Tudor were not received before Christmas. I understand there was a storm but that was 3 weeks ago. What happened to all the mail in the box ? The box is still there it was damaged in storm, etc. I called the post office and they will not help me. None of my checks were cashed or received my gas, electric and car payment are late. The local post office on South Park does NOT answer phone, I called 10 times. The post office and postal service is a joke and they want more money? Not worth it.


I love my Job... Happy Holidays .... Here's yer Darn mail !


Terrible. I have confirmation email to have certified mail delivered and it never was. Called Southside office treated rudely. I want to file written complaint told me don’t bother it comes back to her


No one answers the phone. Tried for two hours. Can't get held mail delivered as requested.
