[Resolved]  Fedex — Package deliver delay

My package was delayed too late. After FedEx picked the package, (per tracking info) it sat at their distribution center for 3 1/2 days w/o move it, and then came to close by city then to different state (2 states away from my state) and no update no more. I've been notify on text that it will be deliver on a giving date and an adult signature require but never show up. I expect my package 4 days ago and never show up. I called the customer support and he said they are committed to deliver customer package on time. This is not the 1st time, my previous package show out for delivery but it arrive 2 days later. Fedex is very poor service
