Flipkart — Issue regarding delivery of product

Hi,
I have ordered the voltas 1.5 ton inverter ac on 23 june and 3rd july was the expected date of delivery but they did not deliver the product on 3rd july and given the promise date of 6 july. Moreover, i called to them and everytime they said we are communicating with courier partner and your product will be delivered soon. At the end, they given promise date of 13 july and said that your issue regarding delivery of order will be resolved for sure by 13 july and you will get your product. But same thing happened again, they did not deliver my order and the status of order is showing in haryana from 25 june.
