Citibank — amount debited from blocked citi bank credit card

Address:

Hi team,

I had blocked my citi bank credit card month before but today i have just received notification of amount 665euro debited against my blocked credit card no.
When i call to book complain, they are saying your card is not blocked for auto debit option so even card is blocked, still transaction can be carried out. Now it is frustrating that if we blocked the card means no transaction ca be carried out in any sense. They even not informed me when i was blocking the card regarding this auto debit option, now they are blaming me that we have informed you which is not true. Technically when someone blocked card that means he has doubt of suspicious transaction can be carried out. This transaction is carried out internationally so it will be not easy to handle it. Please look this matter as i will not even pay single penny because of bank fault.
