Food Panda — order not received and application is showing order delivered

Address: Ghaziabad, Uttar Pradesh, 201010

I have recently booked an order and after waiting approx 40 minutes when i check the status it shows delivered.
When i contacted the support on chat they replied that we are checking and disconnect the chat.
My previous all orders also cancelled by the foodpanda and reason shows the unavailability of riders and refunds also pending since more than last 8 days.
