Flipkart - Not yet received the refund amount

I had purchased a minute ** inch TV from Flipkart on ** November ****. On that day I have cancelled. On the next day I called to Flipkart and they told me u would get your refund within * business days and they assured me on or before ** November u would got ur refund in bank. When I did not get every day I used to call Flipkart including today **/**/**, when I call to customer care they first tell that we are very sorry for ur inconvenience and extending the date regularly. Please I request to all customer that never buy a product from Flipkart if u may cancel that order. U will never get ur refund in the stipulated time that is given by Flipkart.In this case Amazon is far far better option.
