Vu Televisions — wrong model supplied

Address:

Bangalore, Karnataka, 560035

I bought a vu 65inch tv, just one week before. The company sales person recommended me to buy from it's distributor baron electronics in electronic city, bangalore and not through online flipkart.
Baron didn't had a display piece and they sales person said this is new latest version which can connect with our iphones and many other things. But when the tv was installed the service person said that it has very limited things which will work. Instead i should have got the android version for my requirement.
I felt cheated as this tv doesn't meet my requirement. I spoke to the sales person and he agreed the mistake and said he will speak to baron electronics for replacement. But the baron people were very rude and said replacement is not possible and i need to pay them 2 times the gst amount, incase they agree for replacement.

This is all open cheating. How can i get justice and get these culprits punished.
