Bad service and lying to a customer

Bluehills store Ordered 2 pizzas at 18:39 Delivery arrives at 19:55 with only 1 pizza - driver knows nothing and cannot help me. I call the store, they are very sorry and will send the pizze immediately. They call me back in 7 mins to say it is on its way. (20:02) At 20:27 I loose my patience and cancel the remaining pizza and ask for a refund. Bluehills store is literally 4.3km (8 mins) from my house...
