RBL Bank — Credit Card ending with 4955 got permanently suspended without any specific reason

RBL Bank issued me the above-mentioned CC the previous month and permanently suspended the card without any proper reason on 8th Dec. While talking to their customer service they are also not sure about the reason. Now Bank Representative is requesting me to make the payment on the card of Rs 11852.34. I am unsure of this amount as I do not have any transaction details as well as I am unsure if I make a payment on the card will that gets credited or not. Please have a look into this and request RBL to provide a proper justification of my suspended card as well as to provide the transaction details. if the card is getting permanently suspended within 20 days, then they should not be charging any Card Fees also
