Policy Bazaar — Non refund of Processing fee,GST Interest

Policy bazaar excutives Mr Sandeep promised me that if you pay insurance premium of Rs.49704/- for 3 years through credit card you will get interest free EMI. As per his instructions i have paid my HDFC ERGO health insurance policy paid for 3 years of Rs.49704/-. But i knew that through my monthly bank statement the above said amount is EMI with interest. Many times i begged and requested to refund of Processing fee.GST & Interest to the policy bazaar but they are not ready to listen customers issues. They are not proper responded. I have sent all the required documents but they were not examined properly. Kindly refund the above said amount otherwise i will go to consumer court.
