The Los Alamitos post office provides the worst customer service ever! They have a drive thru to drop off your mail, but every mail box in the drive thru has duct tape on it saying "OUT OF ORDER". How can a mail box be out of order?? Just unbelievable!!


I have given Los Alamitos post office several opportunities to deliver my parcels correctly as to not leave them in an unsecured area at my residence if no one is home yet they continue to leave them there and they keep getting stolen! I've placed several notices on my door stating please do not leave packages at my front door for they are being stolen yet the postal carriers continuously disregard said notices, I went to the post office personally to leave notice for the carrier's not to leave packages at my door yet my requests have been ignored!
