[Resolved]  Hitachi — Fake product/not working

I recently purchased an air conditioner from hitachi (Rau518hud)(Window ac 1.5 ton) from a store in new delhi. As big electronics products come packed, i came to know about its problem after its installation. Just a second after the agent turned it on, he himself said "i think it is not cooling !!" whoa!! What? I bought a new ac and now just seconds after turning it on, it is not cooling. Also the ac is too much noisy. I complained about it to the vendor, he said it is company's headache to take on this matter from now. I was really shocked. Only 3-4 hours after buying it, the vendor denied to replace it. I then contacted hitachi, they send their two technicians to work out the problem. They then said "there is no gas inside the compressor pump, how it will cool then?" !! They just said what is unexpectable. Hitachi manufactured and delivered this ac without checking whether it is working or not? How hitachi brags about its quality, but now what happened? At last after 3-4 days of headache the technicians fixed it but i'm still disappointed about their manufacturing quality. They should check their appliances before passing them out of their facility!!!
