Policybazaar Sold fake policy and not issuing refund

I purchased car insurance from policy bazaar. Their executive called me and gave me wrong details for policy. Trusting them as a brand i purchased policy. I called their customer care and they informed me that policy issued is not appropriate and any claim on car against damage will be rejected for sure. I requested for amendments in policy for correction but no reply from them. Then i requested for policy cancellation – policy is cancelled but policybazaar is not issuing refund. Every time i call their number i get same reply that update will be given end of the day. This is a fraud company, they take money from customers, sell fake policies and do not issue refund after cancellation. I am badly stuck with these fraudsters. I need my refund at any cost.
