RBL Bank — Stealing money from my supercard credit card

RBL Bank has stolen money from me under the pretense of insurance, around 730 was debited from my account automatically without my consent for r shield insurance, as soon as this happened I called the customer care number and told them that this money had been deducted, they said it's from their side and they will cancel the insurance since I did not want it, what's worse is they don't inform the customer that they did this and that the customer has 30 days to cancel the insurance or else they automatically purchase it, I had applied for cancellation of the insurance within the 30 days period but then after 5-6 days I got a message that it could not be cancelled, so again I called and told them to cancel it and again they told me to wait 5-6 days and yet again I got a message that it was not cancelled, when I called again they said 30 days has lapsed and I cannot cancel it anymore, I tried around 10 times within a span of 3 months to get this insurance cancelled from my card but rbl bank did not process the cancellation, so now I'm so fed up that I'll pay the money that was taken from my account and I'll get the card cancelled, I don't want to be the customer of a bank who steals money from their customers, I never knew rbl bank was so cheap that it has resorted to these tactics to steal money from customers, as of now they cut Rs. 730 so who knows in the near future they'll cut Rs 10000 for some insurance I didn't apply, it's better I pay the 730 and be done with RBL Bank, I hope this bank gets bankrupt and gets merged with a more honest bank, if anyone reading this has an RBL Bank supercard then please cancel it immediately, the bank will do to you what they did to me, check online and you'll see so many customers have the same complaint, I'm not the only one, as for the bank, I hope you guys rot in hell
