My vehicle number up32gu0297. Service center - goel motors. Hero sales and service vikas nagar lucknow. I have given my vehicle for servicing last month. One months is also not completed after the service. Suddenly my vehicle was not working. It was not starting. I had gone to far place for my work and had to return by dragging the maestro edge of mine. Then i had shown it to local mechanic he said that the spark plug was defective. Then he had changed it. It's your responsibility to provide the vehicle after proper examination. I am paying an amount of rs. 360 around for just service. You are not doing it for free. But what the # service they are providing. I will never go to this service center again in my life and will suggest everyone not to go there.
It's my humble request to you please do something for me
