They are complete fraud. you order with them and restaurant people dont care since it has been discounted you get a discounted service and food.
Please dont waste time and effort with these guys as they dont provide any service worth mentioning. specially if you order for domino s deals, the domino people will make sure that you get a delayed service and that too wrong order.
I think it is a deliberate thing. if you contact food panda they say we cant do anything about the service providers and you should contact them directly . whats the use .
