Food Panda — Not returning money

Address: 411003

Website: www.foodpanda.com

Hi,
I had ordered food through Food Panda site from Eatsome Restaurant in Pune for 180 rs a month back.But due to some payment gateway issue, my money got deducted but my order was not confirmed.
So after that till today I have contacted the Food Panda Customer Care for 5-6 times, but they are not willing to return my money saying that It will take 5-8 business days...but it has been 25-30 days and i din't hear anything from them.
So requesting you to sue them, so that they can't cheat with anyone else like this in future.
Requesting for prompt action against them.
Thanks.
