Maruti Suzuki — problem not rectified

got my eeco model2010 repaired at authorised dealer having noise problem and paid the amount of Rs11500/ and then 3700-00.but the problem is same and noise is less upto 30% only. on complaint they say we are satisfied but i havent spend the money for their satisfaction & moreover they ask to change anew part on every visit. so this is kind request, ask someone to just rectifie the problem
