Hello sir/madam
Iam ajith kumar iam one of the customer of bajaj. As i left my bike for 2nd service, i had problem in my bike in engine area (Tapnut noise sound) i have informed to sevice manager mr guru (Pallava motors chengalpattu) but he is not taking as a serious problem but iam facing problem for last 4 months and they were answering very cool and the service was very bad and poor but they were charging for free service from 700 to 10000 they were not working properly and the concern should be cleared lively in front of me lively if you were taken it seriously they will face very big problem or else i will go consumer court.
