WTF USPS!!

So I have a side business making jewelry and order beads from various countries. I make sure I get them sent to me registered mail so I can track them because they aren't cheap. The last two times I tracked my packages, the day they were to be delivered I happened to be home and the doorbell never rang. Later that day on the USPS website, it says something to the effect of delivery attempted, notice left. I would only be minorly annoyed with picking it up at the post office, but there was no notice in my mailbox, so I can't even do that.

The last time this happened I scheduled a redelivery online, got up early and sat on my porch until the mailman arrived. I asked him if he had a package for me to sign for and stammered it was back in the truck and he'd have to bring it back when he finished my street. I said on, just ring the doorbell and I'll come down and sign. About 15 mins later I went back outside and saw him walking away with my package and hollered to him. He again stammered and said he didn't find the doorbell. I told him it right next to the mailbox and showed him. He was just acting strange all around.

So this past Friday the same "notice left" message on the site with no notice in my box and now I guess I'll spend the morning on my porch waiting for him fuck this makes me mad. What's the problem here? Is he too lazy to ring the freaking bell, too stupid to figure out how or is he dumb enough to try to steal my stuff even though it is registered? What really burns me is my lost income due to this asshole who is easily making more money than I am working 2 jobs and he's too lazy or stupid to even do a basic task. The other thing that bothers me is what else isn't being delivered?

Anyone here work for the post office and try to give me some in site before I file a complaint? Grrrrr!
