Flipkart — Promised offer not given

Address:

#14/1127, Nandhanam, Lenin Nagar, Palayam

While purchasing the product, there was a offer listed in the Flipkart website that "Get Mi Wifi Speaker at Just Re.1" . The Conditions for this offer is, the customer can order this speaker for just Re.1 once the return period of the main product is over. In my case, I have confirmed with the flipkart customer care after placing the order on 22nd Sep and got to know that the said offer will be reflected on my account after the return period is over for the main product ie on 2nd of October. But I didnt get any updates after 2nd also. I have contacted Flipkart Customer care and complained about the same, they said the issue is escalated and will get resolved with in 6th October. B I was following up with these guys in a daily basis and they have no updates regarding the issue rather than asking me to wait till 6th October. And today the waiting period is over and they are telling me to wait for one more day that is ridiculous. Please look into this and if they are not capable enough to fix this issue, please arrange a return pickup for this main product and refund my money back
