[Resolved]  Skoda Laura — Warrant Void of Skoda Laura

I bought a Skoda Laura from channel motors Haldwani (Uttarakhand) on 09.march 2010, registration no UK04H5850, chassis no. TMBCSA1Z8AA150444. Some noise from left excel was coming and i send my car to Jai Auto, Mathura road, Delhi on 09 September 2010 on jobcard no. 3431 as i was on a trip near Delhi. where Jai Auto says that your car got repaired outside authorise service station and have some local parts inside excel and hence your warranty is void. The part costs Rs.23000/-. But it is not true.
I also launched a complaint at Skoda customer care with complaint no. TR6766 but got not a single response till now.
Now either Channel Motors Haidwani have changed excel or many other unknown parts before delivering it or Jai Motors Delhi is saying this in interest of selling his parts but still my excel is not replaced and the car is located at Jai Auto Delhi's work shop.
Plz solve my problem as soon as possible.
