Food Panda — order cancelled after getting it confirmed

Address: Thane, Maharashtra, 400602

Website: www.foodpanda.in

I am foodpanda's one of regular customer. My order got confirmed from foodpanda and after waiting for more than an hour for the restaurant which is supppose to deliver the order within 30 minutes, my order was not delivered.
After making a lot of inquiries from the restaurant what i get to hear is that, "they never received the order and sir, why did you ordered from foodpanda, use our mcdelivery app."
Now, the question arises, when mcdonald's never received my order from where did i received order confirmation mail and even after waiting for more than a hour why did not i received any call from your executives when you give promise to get problem resolved within an hour.
