Query: Amazon!! You are Begining To Slack off :Service Review

The item is ok but delivery service is unhelpful. They left my package at my apartment office and never left a note .. so i have been running around for a week and a half trying to figure out where my order that i needed for my exams was dumped! The online tracking service gave a name that i was not familiar with until i finally went around asking to my annoyance( i shouldn't have to do that i pay you to deliver). learn something from Fedex and UPS. Leave a note on the door so i know where you left my package.
