[Resolved]  HDFC Bank — credit card blocked

I have hdfc credit card i haven't used it once. I am getting a msg for paying 2142rs for some insurance. I have got my card from bank itself. While giving this card they haven't informed me about any insurance. N when i called customer care they said they don't know.. Bank people have blocked my card for not paying that amount. I was in bank at that time n they said bank people have no rite to block credit cards they can only block debit cards that also if customer is giving in written with id proof n all.. So i don't understand without information how u can block someone's card for no reason.. So i am not ready to pay this amount because they haven't informed me anything regarding insurance... I want my card to be unblocked or u just close it.. Because having a card but can't use it.. So there is no use of it.. And customer services people have no sense to talk and they don't know how to solve problems
