Mail carrier shows up to deliver my mail ends up pushing my trash cans with his truck, instead of getting out to put my mail in the box, and he leaves it wide open instead of closing it... i think this is incredibly rude and disrespectful of him. And a formal complaint needs to be filed against him..... Alamo ca


Please hold mail from 5/26 to 6/3. Thank you


We have an Alamo business and were sending a lot of mail (first class) Tuesday Oct 11. Nobody delivered or picked up mail Our office was open the whole day.


I received a voice mail from this post office and called them back several times and nobody has ever picked up. There is not even a answering machine, where I can leave a message. I do not like USPS and have had nothing but bad experiences.
