RBL Bank — rbl bank credit card bill received without activation

Address:

THE RATNAKAR BANK LTD,ABW TOWER, AT IFFCO CHOWK,VILLAGE SUKHRAULI,NH-8, GURGAON,HARYANA - 122002, 122002

RBL credit card delivered to my residential address, but we rejected and resend it back. I have sent mail notification for to terminate and cancel the card.What is the reason for bill generation and cheating a customer.

Card is not activated but bill is generated - Total Amount Due: Rs. 1178.82
Minimum Amount Due: Rs. 379.82
Payment Due Date: 07-Feb-2020

Seriously this has become a torture.

Customer care is not available for this purpose.

Expecting a positive reply,

Regards,
Sunil Kanneri.G

Can I opt for legal action?
