Poor Delivery Service

I have been a very satisfied customer of Loot for over four years now. Unfortunately that changed today. A package I have ordered, has not been delivered today as promised. I'm used to "your order is out for delivery" emails, I receive my packages on the same day. Loot is using a new courier company which is absolutely pathetic. You can't even track your parcel! Please, Loot, do something about your poor courier service or I will take my business elsewhere!
