SBI Card — Given wrong sbi credit card and now they won't cancel the card

A month before i.e. in March an SBI card sales person offered me sbi octane card, he took my Pan no and processed for the card. After a month I received the card at my home address. To my surprise when I open the envelope I found sbi max card.
I raised a complaint on this to close the card on 30th Apr. Within few days I got the bill generated for the new card which isn't removed from the envelope also.
After a week I receive a sms stating the card cannoy be closed.
