Flipkart — Not providingRefund

Hi I have ordered a product on 28th February it was given a delivery date of 11th March. But from 11th I am facing a Worst service I have ever seen I have ordered it more than a month ago not yet delivered when I contact customer service they come up with some exclution and provide deadline like 11, 16, 19, 21, 24, 27, 29... These are the number of excalation resolution dates. But nothing happens when I spoke with senior executive they also say the same thing if they don't have any answer they simply cut the call.nsumer forum
I haven't seen such a pathetic service. Please cancel the order and provide me refund.
