No delivery – DoorDash - Food Delivery Review

I ordered from Door Dash and I never received my food. I was unable to contact the driver and it took me 30+ minutes to get in touch with someone from customer service. After it was 1.5 hours past the predicted delivery time, they offered me credit to door dash and i had to ask for a refund. They never explained why I did not receive my food. I would appreciate an explanation.
