ThursdayFeb 14 at 5:50 no mail delivered yet!!!!!!! Its day for local paper ( which is hit or miss delivery) so I should at least have that mail today. Poor delivery service


Just tried to mail a package and this Carnegie post office is closed even though the hours state 9-12 on Saturdays and it was past 9:30 am. I waited about 15 minute and nobody showed up to unlock the door. I thought it could be due to Columbus day weekend but other post offices are open such as Glenshaw.


My package from Kohl's was not delivered to my address although I received notification that it was delivered at 11: 07 Friday, July 7. #420152209261299995669264729837
