Bad service by dealer

Your authorised dealer Chittosho Motors C.39, Phase 3, (Indl. Area), Mohali, Punjab is rendering services to the Marut customers. I purchased Maaruri Swift Udi (Diesel) in December, 2008. Got two free services done from your above authorised dealer at its worksho: C 147, Phase-7,(Indl. Area), Mohali. The dealer failed to replace the Dicky lock, which became jammed. The complaint was made to the deaalers Service Advisor Baljeet Singh - Gautam - on 22.07.008 but failed either to give satisfactory anaswar, or repair the lock or replaced with a new one. The vehicle is within the 12 months warranty. Please give a suitable direction to the dealer.
