RBL Bank — credit card bill received without activation

Website:

[email protected]

I received RBL credit card 2 months back. But not activated. But bills are coming. Because of their torture, I paid Rs.783/-. Next month again torture. This time I paid Rs.273/-.

I want to cancel the card. Customer care is not available for this purpose.
I have sent 3 emails. But no reply.

Can I opt for legal action?

Dear sir,

I have not purchased anything using your credit card.

I have not even activated your credit card.

Kindly cancel all the bills and stop sending further emails and messages.

Expecting a positive reply,

regards,

s.selvakumar
