Amazon Moderation Is A Joke

I purchased a Antson Helmet Cleaner after checking good reviews. I usually buy a different product but it is slightly expensive and comes in 125 ml can whereas this Antson was coming with 250 ml spray bottle. Upon receiving the product i saw a small card saying that they will give 50 rs cashback on good reviews. Now i know this is a lot common and so many seller does it. Problem was that when i tried to notify amazon by submitting my review,they rejected it. I even reached out to customer care and they basically yapped about escalating it and what not and even asked me to fill a form. But nothing has happened. Please avoid this if you happen to buy. Its literally shit for 299. Tldr : Bought a shitty product from amazon whose seller gives cashback for fake reviews. Amazon did nothing about it
