Hyundai Motor India — Vehicle Insurance Policy

I have booked Hyundai Creta 6 months back at dealership Ishanya Hyundai Ambegaon katraj Pune..
That time I had called customer care before booking and asked that is it mandatory to take insurance policy from Dealer..

Reply of Customer Support : It is not mandatory, customer can take Insurance Policy from Anywhere where he thinks fit..

But now Dealer is unnecessarily forcing to take Insurance Policy from himself which is costing me 30, 000 extra..

Also in IRDSI guidelines it is clearly written that Dealer cannot force customer to buy Insurance policy from Himself..

This is Blatant violation of Govt Rules what should a customer do now..
