Maruti Suzuki India — ritz vdi abs car defective silencer-request

I purchased a new maruthi ritz vdi abs car bearing reg. No. Kl-64 a-2125, chasisno. Ma3fdebis 00420226and engine no. D13a 1999995 from indus motors muvattupuzha kerala in dec. 2012. The whole services of the car has been done at indus motors only till now. Durig the usage period the silencer of the car had been badly damaged because of the manufacturing defect. I made complaint before your good self on7/5/2016 and 17/5/2016 respectively and the same hasbeen solved by replacing a new modified silencer at company's cost. Now the replaced silencer has been damaged, as happened earlier. I brought the matter before the dealer, but they mercilessly refused to replace the same by company's cost. Hence i request your good self to kindly rectify this manufacturing defect at the earliest. [protected]@gmail.com
