Always friendly, but not really helpful. Time and time again we get the run around, wrong information or no information at all. And worse still, is being told over and over again to go to the Westminster location if we want better results/service, only to get worse results/service there. The 3 stars are for the politeness but overall, it could be better. Maybe we just need to accept the limitations and low expectations that has become the USPS.

If you ever need proof what's wrong with the US Government, visit the Seal Beach post office. The absolute worst service and operation imaginable. It would serve the community better to shut it down then have people frustrated.
