Food Panda — payment done but food order not delivered

Address: Kolkata, West Bengal, 700091

Website: www.foodpanda.in

Hi,

I have ordered one item via foodpanda mobile app. Order id is 'y8zj-kv0w'. I made an online payment for this order using net banking.
After i placed the order, the order went through all the status, and suddenly changed to 'delivered' status. But neither i received the order nor anyone called me to receive the order.
I have already paid money and never received anything for it.
I have already tried to contact the customer care, but noone replies to my messages (Online chat support). I have also messaged to their facebook page, but no response. I did not found any customer care phone number.
Please look into the matter.
