Flipkart — Continuously ignoring and delaying exchange

Address:

Katni

23I have ordered a phone in exchange during the sale period. Phone delivered on the date told but the exchange is not processed till date. When i tried contacting them they told its a mistake we will arrange the pickup within 24 hours but nothing happened. later i found it got cancelled on their own thus i tried contacting again and this time i lodged a complaint with complaint number IN[protected]. still problem is not resolved as in this complaint they assured me 72 hours for resolution. moreover as every company records call for training and quality purpose i want them to listen to my recordings where they just pickup the phone ask about the complaint and put me on hold for 10 10 minutes. this is ridiculous, disappointing, disheartening, immoral as well as mannerless. kindly look towards this as a serious issue and provide me timely and correct remedy.
