I have ordered something from flipkart. Expected delivery date was december 5, 2019.
Courier service called me for delivery on december 4, 2019 but i couldn't pick up the call but i called back (At 2:30pm) after one hour of his last call. This time the delivery person didn't pick up my call. So i waited for next day (December 5, 2019) for his second delivery attempt but i didn't receive any call. I tried flipkart feedback option in my order page to ask for the courier company's contact number but couldn't get it. So then i called flipkart to resolve this issue. The flipkart representative asked me to wait until the next working day to receive my parcel. He assured me that i will receive my order on the next day. I talked to the representative at around 5:00pm on december 5, 2019. 6 hours later at around 12:30am on december 6, 2019 i received an email regarding the cancelation of my order. When i asked about the reason of cancellation the flipkart executive told me that it was the courier company i. E ekart logistics who cancelled my delivery and marked it as rto and the reason they have mentioned is "customer rejected the order". Which is a clear lie. Is it fair if the service provider lies and the customer has to pay the price. And is it fair if they get away with it after doing so. I can prove everything i have said. I have all the call recordings, screenshots and all. There must be some laws against these things. I'm expecting a solution here but if this is not the right place to bring this issue then i would like to know where i can resolve this matter legally.
