[Resolved]  Voltas Vertis Elite 1 Ton / Split — Worst A/C Ever - No cooling/gulps power

I recently bought this Voltas A/c from Vasanth & co in chennai, Since the day i have installed it there is been no cooling atalll...it takes three hrs to reach 26deg...When i complaint this, one service person (looks a lay man) came and checked it and told us A/c is fine but my room has lot of vents for cooling to escape. Now i have plugged all the gaps and done carpentry corrections, but still the performance is the same - worst. My fan work much better than this A/c.
For everyone out there, please never ever think of buying Voltas A/C.
I don't know how they are still in businees with this kind of product and service.
