[Resolved]  Flipkart — Defective product and bad service

I ordered a voltas 1 ton ac from flipkart with product id (Od[protected] on 24th march 2017 and after the ac was installed it had many defects, in short the whole ac was defective and this was acknowledged by voltas team and after finding this, i requested for a replacement on march 28, 2017. Till now (24 april 2017) i have not got the replacement and flipkart is just harassing me.
Even after agreeing to replace it by april 19th, they did not replace instead they postponed the delivery to 29th april. I am suffering because of hot weather and bad service.

Can flipkart please refund me charges paid towards installation of ac, then unistallation of ac and defective product and also componesate me on mental harrasment and my phone charges for calling them day in day out.
