HDFC One Assist — Deactivation of credit card

I Received SMS from HDFC BANK that RS- 4854.47 is to be paid for my credit card(card numbered XX4466) to ONE ASSIST PLAN. Ive never used my credit card to pay all this due. I never gave any consent for renewing my card. Ive closed my account in the bank few months back but i am still receiving this message asking me to pay immediately. Ive also filled a form in the bank to deactivate but it failed and the process was stopped. Ive never used the card or it is of no use to me . i dont even know the company and this kind o[censored]nsolicited due for payments of my credit card is not really an acceptable act . So i kindly request you to deactivate ASAP. (Relationship no. 6280441) i am very much irritated by receiving the calls and mail from Hdfc cards. ASAP please cancel my credit card.
