Food Panda — my every orders get cancelled and amount is not getting refunded

Address: Mumbai City, Maharashtra, 400059

Website: www.foodpanda.in

Up till now, i have ordered many things but almost all my orders get canceled and the amount also not get refunded yet.
When i place an order it takes orders after sometimes it moves ahead i. E it shows progress in the app about food delivery, but after waiting for more than 2 hours it cancels the order, as if we are mad waiting for foods, our lunchtimes get over, we face too many problems related to this.
It's not like this, that it happens 3 to 4 times, it happens every time.
And even their wasting my coupons,
