You guys continue making mistakes!! My packages are going somewhere else and I keep receiving someone else's packages. The subdivision has been here for 1 year!!! Can you please become more efficient??


Don’t know what is going on , But we should get are mail when people or business mail stuff to us.. I know I’m not the only one in town haven problems getting mail delivered And packages to house.. I can’t even get them to answer phone to asked where they have delivered my packages at.. It’s sad the we have post on are Sourlake website to ask if anyone has are packages... When it is the Post Office duty to Deliver are package and mail.. They do get paid to do a job..




I’m perturbed by the hours the sour lake TX post office does business their indoor sign states they’re closed from 11am to 12:30pm. Wow what a fabulous lunch break. Bankers hours. No one has thought of alternating lunch breaks? That way when I make an 8 mile drive from the countryside and it’s unfortunately 11am I don’t have to kill an hour and 1/2 waiting for the window to open. What’s the deal here? Who makes these brilliant decisions?
