Policy Bazaar — Unauthorized transaction for policy renewal from credit card

I had taken a term insurance policy with ICICI prudential through Policy Bazaar last year and had paid the premium thru a Credit card. Afterwards, I came to Canada with PR visa and couldn't go back because of Covid-19 scare. Without my authorization, the policy renewal premium was paid and I even received no notification of the transaction. It was brought to my attention after I saw my credit card statement for the month.
When I spoke to the customer service, the representative informed me that all credit card payments are put on auto-debit mode, which is bizarre as I wasn't informed or asked for authorization for the same. Further, they can't reverse it as the payment is made to the insurer company. The insurance company has the policy of no refunds post payment, which is again a fraudulent.
