Flipkart — Flipkart selling branded products open sealed and not taking return

Hi

I have ordered herbalife protein powder. And seller name PDCOMPANY01 selling herbalife open products on flipkart.

I have raised replacement and received same open sealed product again.

After that I have raised so many return request but flipkart did not return product and not returning my money.

Flipkart is so careless that he is not able to take any action against their seller

I want my refund back and strict action against seller PDCOMANY01
