Food Panda — refund is not given

Address: 600117

I have ordered food from food panda on 18th oct 2018. They called me after an hour and said they want to replace the order as no executives are available. Again they called me after another hour and said the same. I told them to cancel and refund my money. It is not yet refunded till date 22 oct 2018. I have raised a request on their app. No response is received yet. I don't find any way to contact the customer care person. I don't want anymore people to lose their money to this fraudulent. Please help.
