Food Panda — my amount is not refunded

I placed my order from masala potli of Rs 140 on 20th October through food panda. They cancelled my order and now every time when i ask for my refund they keep asking me to wait for 7-10 days. I have talked to their executive several times. Every time they say that your refund has been initiated and you will get it in 7-10 working days. Today is 15th October, its almost a month still they haven’t refunded my amount.
