Why iterating hours don't match with actual closing times. I passed by the Post office yesterday 2 minutes to four and the door as locked. The latest last week was at 4:30 and also.lockrd. No good for business


I went to pick up a package on Saturday august 5 2023 at 11:59pm. The employee was at the front counter but the door was locked. I show him my slip and only told him I wanted to pick up the package. He told me they were closed and would no give me the package which I really needed to have on Saturday. Customer service skills are non existent at this post office. Please re train employees on how to handle customers in the future. From 1 to ten you get a 0.


Tracking package


Dear, tomorrow I will be passing to withdraw the USPS shipment N° 92005590109084001691339 by the branch of Guanica.


I have lived in the United States and the service is more updated because it when they came bundles large in mailboxes had a mailbox great for deposit the same and you left a key to sucrase the package and one returned the key to the mailbox big is an advantage for the postman as for people and you don't have to be behind the postman or go to mail quite far is thank...
