Bajaj Finserv — EMI card charges (Card No.[protected])

I have been pursued by one of your marketing guy to avail the EMI card which is hassle free and no hidden charges and can be utilized as and when required. I told him - i don't need this card as i am a retired senior citizen and surviving on my small pension amount, even after that he pushed me to take the card as an special request. I had never been told that Rs.99/- to pay for keeping the card which is of no use for me. Kindly STOP recovery and tell me how i can send back your card which has never been used till date.
