Food Panda — food panda put me in a humiliating position

Website: Food App

I had ordered food from a restaurant thru food panda app on 11 august where i had guests come in. The time for delivery was 1 hour. First of all the food panda rider didn't reach the restaurant and denied taking the order and cancelled it and this wasn't intimated to me by food panda and on asking for a call back from food panda the executive lied to me saying that the order was cancelled because the restaurant is closed when it was their mistake. Also on callback by food panda i was informed much after the stipulated time that the order has been cancelled and they also denied refunding the amount to my account immediately and the executive abruptly cut the call. I urge and strongly advise all not to use this 3rd grade app and be cheated and humiliated.
