Foodpanda — not delivered the food but shown in a system delivered

I have ordered the food, they did not come to deliver the food, not even customer care responded even they closed the complaint stating you received the food, however i was keep on stating i did not received the food, even the delivery guy was asking they dont get salary from 4-5 months, hence they won't cancel my order. However i waited for food an hr after picked up the food.
