Flipkart — game reward not received

The flipkart gamezone is fake they don't provide they don't give the rewards.
It's just luring customer to be activated on flipkart app.
I played a quiz game on 23 sept @8pm i won ambrane powerbank.
They told that i will receive by 9th oct my reward on my flipkart app itself from that day till today am continuously checking whether i received my reward or not.
I complaint to customer care on both mail and on call.
They told that i will receive it within 24-48hrs.
Now 48hrs have passed away till now they neither credited me my powerbank and nor my supercoins around 250-300 coins i won.
I have lot of others works to do.
Customer who are reading this i request you all also complaint so that the people who don't know about their scam may come to know.
What this flipkart is actually doing with their customers
Am complaining here for the last time.
