Policy Bazaar — refund of credited amount

On 31 oct 17 i have paid 7439/- through online link to policy bazar.com to buy car policy but due to some technical reason policy was not done... After 2 days i have to buy another car policy through policy bazar. But the amount which was credited on 31 oct 17 is still not refunded... I have launched complaint to my bank service and they reply that refund will be done from policy bazar only.. I have again complaint to policy bazar but no response comes from their side plzzz help me to solve the problem
