Mail to Muirwood Square has not been delivered for a few days. No notice given and can't get anyone to answer at the post office. I work all day and can't get to the PO before they close to find out what is going on. Poor service!

There has been no delivery of mail to my house for 4 days. This is not acceptable. I expect one day every so often to be missed, as I've heard that the postal service in Martinez is not so reliable, but FOUR days? I've been expecting two important deliveries for a week, and I am quite concerned.

Delivery person is a liar, was home with lights on and heard mail delivered but not the package that was tracked to be delivered. Tracking, says "attempted delivery and left a notice". Lie. No notice left. No doorbell rang, no knock.

I was expecting a package to be delivered on Saturday, tracking said it would be here at or around 3 pm. Waited for it, never came, checked tracking, still said in transit. This morning, I check the tracking, says attempted delivery and left a notice. No notice to be found. I can't believe how bad this delivery service is. And this isn't the first occurrence of poor service.

Old motto - Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds. New motto- Its a government job. Poor service is not only expected, we require it.

I haven't received any post for 4 days...not a flyer, nor junk, not a bill to be found. Just nothin'. I have important things I'm expecting. I swear the dude only drops to 2 or 3 houses of his choosing and then kicks off for the night. Sometimes, if he can be bothered to show up at all, he wont rattle down the street until 8 pm. Not cool, Martinez postal service. Not cool.

So I put out a bill to be picked up on Saturday. It was put out at 8 am on Saturday with the flag UP and I come home on Sunday at 3 pm and GUESS WHAT my bill is still in my f***ing mail Box. I will be calling the Post Master and complaining again about what idiots that run the Martinez post office. I am also asking for my money back as I will have to delivery my BILL on my own. And the government doesn't understand why people are tired of the service we get. I will have to say the people doing our route are the worst, inconsiderate people out there and they all should be fired. Please fired and Re-Vamp the Martinez post office and all the people who work there. This isn't the first of many complaints that I have made and by the looks of it will be continued to make them until something is done. So SAD that these people represents the US Government
