Bata India — Not received the Refund for Cancelled order

I placed an online order from a bata store in Bangalore on 5th of September for an amount of Rs 1699. I cancelled the order on 12th September as I did not receive the item until then. I called the customer care regarding my refund 4 times, every time I call them, they give me excuses stating you will get the link for refund in 5 working days. Its already a month and the chances of getting my refund is zero. There is no follow up from their end nor a proper response. The reference number for my order is 712381 given by Bata. I need my refund. I am stressed out with such a bad experience.
