Very bad experience with Vento

Even though the vehicle is ok, the after sales service is pathetic. I purchased my Vento on 24th Dec'15 and now recently I came to know that they have shown the delivery date as 31st Aug'15. Nobody listened to me even after producing all the proof and denied warranty by their service dealer Automark, Mathura Road, Delhi. I left my vehicle for one day there so that they can check and rectify the system and give me warranty but they did not and forced me to pay the money. After I submitted negative reviews, now they are sending me mails for settlement.

Volkwagen systmes are so bad that a vehicle delivered in Dec can be entered as delivered in Aug. Company did not even know that the vehicle was standing for 4 months with dealer or are they fudging delivery / invoicing data. God knows how many customers they would have fooled like this and denied warranty. I am not sure whether they had given me the new vehicle or this vehicle was delivered to somebody in Aug and returned due to some failure and then they again delivered it to me in Dec. I sent an email to the company and there is no response instead the service dealer is only communicating on their behalf. I am taking this case to Consumer Forum and will put everybody to justice.
