Mtailmodeecom Flipkart — Soundbar purchased, website description claiming wrong

Website:

Flipkart

I purchased zebronics zuke bar 9000 pro on flipkart selling by mtailmodeecom, for the claiming by seller on item description that this product having dolby digital plus technology, but real product which I I recieved is not having that technology instead just having dolby audio, which is of lower grade than claimed one, I requested flipkart with many proof of images however times they asked for, but every time flipkart turned down my claim without any solid reason and citing meaningless and unwarranted reasons
