I would have to say that service and performance has gone way down hill. I sent a newbie package to a fellow member before I went on vacation March 17th, and as of today, he has yet to receive said package. When I got back from vacation I expected there to be three packages delivered the following Monday, as I had our mail stopped. Monday came and went, and no packages. I go to the post office, deal with a rude employee (go figure), was given a number to call my carrier, called the carrier and dealt with another rude employee who said I had to call before 8:30 AM, and then got to speak with my carrier the next day, and boom, there were my three packages that he pulled out of the door from empty house down the road. Oops he tells me.
A week later my wife orders something from Amazon, we finally get the shipping confirmation and tracking number, it shows delivered as of Monday of last week, since I'm laid off, I am at home all day, and guess what, no package. So I call my carrier up again, and as if it were some magic trick, there is our package in his hand, and he even brought it to my door for me.
Over all I would have to say the service is down, especially since the package that I sent to another member had DC, and he has yet to receive it.
Edit to add: When I got back from vacation I had a stack of mail over an inch thick of other people's mail. Not just mail for people, but mail for businesses that are no where near my home.
