Standard Chartered Bank — overdue payment.

Address:

Kolkata, West Bengal

Sir, I've received a threatening message for payment of overdue of my card No. [protected] without mentioning the exact amount to be paid. Unfortunately, PIN of the aforesaid card has not been provided by appropriate authority. In absence of the PIN, the card can not be used either for purchase or for withdrawing cash which I never indulge. In the light of the above how an overdue amount exists? Kindly look into the matter. Yours faithfully Arabinda Chaudhuri
