omg, this is a goverment post office and is so inept that they only score a 1.6 /5 reviews. why is that? in the next town they have a score of 4.4/5. something is wrong in colon and it's not magic. someone needs to get fired, and replaced with someone who actually cares about doing a good job to there community. this not that hard to see what is going on! is there not someone higherup to see what is goIng here? or is that person person in charge don't really give a sh1t? i'am going to guess she is a woman!


Colon postal service has become sloppy and incompetent. Delivering mail to the wrong addresses and constantly losing packages or delivering them to the wrong home. I currently have 2 packages that are MIA. They were scanned 3x after arriving in Colon and say they were delivered to my door on 3/30. NO, they were not delivered. I saw the postal worker stop at my mailbox and they never left the vehicle. The packages were also not delivered to my mailbox. SO, where are they? How long does it take to trace the scans and for the postal employee to know where they delivered them? Ridiculous incompetence! They are making way too much money for the actual job they are doing. I am beyond livid
