[Resolved]  RBL Bank — r shield insurance issues

I opted out of the r shield insurance plan but then i was again later charged 12000 to my credit card. This is fraud. Please revert the money. I am opting out again. Give me the ways to opt out. They don't provide any phone number for calling or sms cancellation. Only i've without the option of cancellation. Please revert my money or maybe i will file a case of fraud against rbl.
