I wish I could give 0 stars. The absolute worst option for delivery. Virtually every single time I've been stuck with dealing with them they are late and or make mistakes. Whenever I see Dynamex attached to a delivery my heart sinks knowing they will find some new way to make a simple task into a headache. They recently didn't deliver an item at all saying they couldn't find the front door, while I have had dozens of deliveries at this address with every other courier company. Horrific service.
Edit - they continue to be the only courier that consistently fails to deliver, absolutely terrible.
