So the day after MLK day the normal mail lady shows up at 5pm and passes my house up. So I stop her and tell her she forgot my house and she tells me that they are splitting the houses up!. So it makes sense to drive past my house and not deliver/pick up my mail but to have a second person come out for my mail. Then she proceeds to drop the houses mail that’s right next to mine. Here I sit at 630pm with no mail. Maybe she meant I’ll get two days worth tomorrow. That could be the dumbest idea I’ve ever heard.

Call the post office with a problem? Forget trying they don't pick up the phone, been trying repeatedly all day long. And the email address for the local postmaster on the website bounces.

Rude employee. Just asked a simple question and responded with sarcastic responses. If I didn't know anything the least she could've done was be nicer about it. Never coming here again.
