Vasanth & Co — Bought a mixer performance was really bad.

Address: Salem

I've visited vasanth & co in salem to buy water purifier and mixer..
We have already decided to buy Preeti mixer as we already used the brand.
Sales person however convinced to make me butterfly mixer that's performance was really good, and we have bought by believing it.
But it's performance was really poor, totally disappointed. We contacted vasanth & co, no proper response even after buying 15days.
I've returned the mixer to replace with preeti mixer, still they haven't contacted me to take mixer.
