[Resolved]  Toyota Corolla Ravindu Toyota Bng — Missing problem in the engine

Dear sir
I am owning this Toyota corolla for the past 3 years i have done all the services in Ravinda toyota showroom near iskon temple .For the last 7-8 months i am
facing lots of problem in engine
Some 7-8 months back i noticed mal function lamp glowing in the dash board i immediately contacted showroom in BNG they told me to bring the car. I immediately left the car after checking they replaced the parts & delivered it to me after 6-7 days. On 25th may 2008 my last & final service was due i left the car for routine service. After one month i noticed some missing problem in the engine again i left the Vehicle to the showroom on 4-7-2008 after checking they gave me the report today that the parts replaced some 7-8 months have to be replaced again cost will be around Rs 35000/-. I argued that it should be replaced free of cost because replaced parts have one year warranty. They are not responding properly.
I kindly request you to solve this problem as soon as possible
