The parking lot at this location is just awful! I drove my brand new car thru to drop letters in the boxes out front Sunday night and the pot hole I hit almost swallowed us up! And it's not just that drive thru lane that is bad-the entire place needs resurfaced and soon!

We have not received any mail in 2 days. I call my post office at all hours of the day and no one answers the phone. I call the USpostal service 800 line and the wait is over an hour to talk with someone. This lack of service would not be tolerated anywhere else! Where is my mail? My list office is Montclair

I live in Mayfair and have not received mail since July3. It is now July 9. No one answers the phone at my post office EVER ~ Montclair location. Would someone please tell me what's going on?

Have been calling repeatedly for 5 hours - no answer, just keeps ringing and then a ear piercing tone. They have been holding a package with a wrong delivery zip code for .......................14 days!!!!! Nothing the vendor can do as it should have been returned. What do I have to do - drive 1 hour to get to their office.

We are disappointed this post office never answers the phone. Other post offices do answer but we have tried calling for five days.
