Overnite Express — the slowest company I have ever seen

Overbite express is the slowest courier company. I have ordered my books long time back. It's been more than 12 days now. It's been in my city since 5 days but still it isn't delivered till now. I wonder why it takes so long to deliver while fedex and bluedart would have delivered within 2 or 3 days of my order. I was sent another courier. I have received that. It's been 6 days now, and the website is still showing that it is out for delivery 😂. The worst courier service company
