Samsung / Ac 1. 5 Ton — Authorized dealer services faulty and inadequate and late

I have purchased Ac of 1.5 ton in 2007. It has failed to work for 3 time in two years. Once it was during warrant period. Once it has failed 10 days back. Service engineeer charegd his fees and changed the spare, but i think its duplicate. Samsung, one of the largest consumer goods company in India runs itd call center till 8.00 pm, its pathetic. Customer who has complaint has to wait for days for sevice while they chage in full. My Ac is not working but I want to take Samsung to court for giving me such a duplicate product. I think these companies like Airtel, samsung are taking people for ride as I am using their service while they frustrate consumers with their service. I recommend that neer buy a Samsunf window AC as I have experienced the product in full.
