New India Assurance — refund pending - car insurance

Address: 603210

I purchased a car insurance for 11875 and cancelled on the same day and was promised for refund in 14 days. However it has been more than 2.5months now and i have not received my refund.

Policy bazaar says refund is pending from bank side. But what is the issue no one knows and are not ready to answer.
All i get is an email with approximate date and that date gets pushed to next 10 days every time
