Policy Bazaar — refund against cancellation

I had issued a car policy from HDFC ERGO
I received a call from your executive regarding to cancel this policy and issue a new policy from new India insurance and i was assured that the amount i had paid twice will be refunded back soon and full amount
But repeatedly I have called and mailed policy bazaar and every time i call I have been assured that it has been done and within 15 days your money will be refunded back
Now after more than 40 days one of your executives told me that money will be deducted from my paid amount which is not my fault
