Rbl Bajaj Finserv — RBL bank

Hello Team,
I am holding RBL Bajaj Finserv super card and I want to cancel the card immediately but there is no proper contact or support from the bank customer care .I have dropped numerous queries in order to cancel but I get lenghty email to follow and call them on provided number unfortunately this number does not allow Me to speak to any of the customer care executive and for my bad luck I have been charged on this card even though I had requested them to cancel on rs.1k change and if I don't pay then it will hit my credit score hence I need your help to resolve this issue . I cannot afford paying 1k to them without using the card and this bank as pathetic customer care service.

And recently I have been receiving reply saying to send email from my registered email id.when I checked the company website the email id entered by them was completely incorrect now I cannot edit them and if I ask them to edit and provide the details they are still drafting the same email each and every time by saying send email from your registered email id. They have taken down Barun instead of Varun. This is not my mistake. And they are not solving this issue by calling me .this is really frustrating.
