Volkswagen India — Regarding defect in my new vento car

Address:

Surat, Gujarat

As above I had purchased Volkswagen vento car. My new car throwing carbon and carbon monoxide from my silencer which is defects in my car. I am called your executive many times from 8th April to 21 April regarding this problem but I didn't get any positive response. I can't believe like you company behaved lightly and didn't solved my problem. So take return your defective car and solve my problem within 7 days. And no any fare decision taking by you than I will take legal action against it.
