Boat — Misleading Marketing

I purchased boat Rockerz 255 pro+ Bluetooth earphones from boat site on 28th December. As per product page it supports aptx bluetooth codec, however actual product does not support aptx. Upon complaining the next day, they asked me to replace the product since it was within 7 days of purchase. The replaced product also did not support aptx. I complained again and they asked me to go for warranty claim. I registered for warranty claim and their courier partner came and picked the product. After a couple of days, i received a mail that my claim has been rejected as it is working fine on all parameters. I had specifically mentioned that issue is aptx not supported. They did not even bother to check it. They sent the product back to me. I complained again and again they are now asking me to claim warranty. They have stopped replying to emails or messages on social media.
