I have given my Wagon -R car for 4th servicing in the last month. After the servicing it was observed that car starts jerkingwhen speed lowers down. Immediately I informed kataria services vapi about this problem. Mr.prajapati attended the problem and told me that he has not observed any problem and went back but the problem remained unattended. After three days I again informed about the same problem to Mr Prajapati and then he agreed to take the car along with him and now he has informed me that there is some problem with the car ignitor and it will cost me Rs 2100. The problem was not there before servicing and it is clearly the mistake from the services side. I have already paid the servicing charges but for problems which arose due to poor servicing how am I responsible for its payment.
