Food didnt come

Ordered food for delivery yesterday. Paid for it online. After more than an hour when the food didnt arrive and noone answered their phones, I decided it's best I take a drive and see what's the story. My food was just sitting there. If I hadnt already paid I woukd have never given Debonairs my money. The food is supposed to be free afrer 40 minutes or if it's cold. Now I am just supposed to understand why my food wasn't delivered to me. Why couldn't they call to tell me they can't deliver or atleast offer a voucher of some sort. Totally unacceptable.
