Bluestar — BlueStar Inverter Room Air Conditioner

I have bought a new Bluestar Inverter Room Air Conditioner a month back and after few days after the installation AC stopped working and we have requested Blue Star to replace the product and they sad they will replace the part. But after few days there was no cooling. We have raised a complaint and a ticket. But they have closed the ticket with a comment, part will be replaced. It is really annoying to say that they never replaced the product which is 1 month old and i am tired of speaking to their experts. I would like to replace the equipment as such, as it seems like they have delivered a faulty product.
