Food Panda — I'm complaining about non refund of my order

Address: Ghaziabad, Uttar Pradesh, 201014

Website: Foodpanda

On 16th oct 2018, i ordered chilli paneer dish on foodpanda app. But instead of that i received noodles n chilli paneer combo which was a wrong order. I lodged a complaint that day only and was given assurance that the money will be refunded to my wallet within 7-10days.
It's nearly 2 months now. Neither have i received my money back nor i m receiving any new notifications of new offers.
