Hyundai Motor India — insurance for creta

Dear Sir,
I have booked Creta automatic Car to S.S. Hyundai Pathanamthitta and paid Rs 825000 advance payment on 13th July 2017. They are not delivered the vehicle as they promised date and now they said car is allotted and confirmed delivery next week.
I found S.S. Hyundai offered insurance is very expensive as Rs 49213. Now I found other Govt insurance Co rates are only Rs 32000/-(Same B to B)
I have informed to S.S. Hyundai today that I will arrange insurance myself.But they are not ready to give vehicle without their insurance policy.Now they said they are going to refund the payment in case I am not choose their Insurance.
This is my right to select insurance service provider.This is absolutely a violation of IRDAI rule.
Hope you will consider this mail and look forward your timely assistance.to solve this issue before going legally.

Regards,
Anil kumar Nair
