- STSeanjohn ThomasApr 11, 20161.0Had a package sent by Amazon ... 2 Day shipping. Package was sent same day and arrived at Southern Ave Depot on Day of delivery. Package was out for delivery at 7am and 5:37pm I received a delivery confirmation text. Note in tracking online states package was left in mailbox. Package is too large for mailbox and package was not left at security shack ... Package not left in business office. Contacted Amazon and they filed complaint against shipper. Post office was supposed to call and never did. Waited 2 days and made sure to run into post officer in lobby. Postal guy said he did not have package but heard I was looking for package. He wanted a text with tracking number number ... SMH ... Walked off ... 4 days later called office and Office manager and delivery guy both have brain farts. Manager keep asking who I work for and what I want even after I explain I'm a customer and looking for my package ... Gave tracking info to Supervisor and Supervisor said hold on I need to print out information. She said package was delivered and I explained that it had not made it ... Supervisor hang up and did not answer phone when I called back 4 times. Horrible customer service and very unorganized. Will have to receive mail at Co workers home to avoid this branch office. This is the 3rd package I have either not received or received late.
