• on 16.08.2019, the courier company’s online status showed "no such consignee at the given address" that means i do not live at the given address where the card was sent

• on 29.08.2019 once again i reported the matter vide interaction id:1-[protected] to the [protected]@sbicard.com to prevent any fraudulent transaction using the card without my knowledge
• on 29.08.2019, on my request the undelivered card was blocked by sbi to prevent any fraudulent transaction
• on 30.08.2019 at 17:24 hours, i received an sms from sbi card that the blocked card was used to pay one “cpp assistance service p” for rs 1699.00 but the payment was declined by sbicard.

How could the card that is in sbi’s custody was used to pay someone?

For information: i never had seen the blocked card, have no knowledge about the pin and the card number except the last 4 digit.
