FNB 'hot-listed' ATM card

Requested for My cheque card to be cancelled after it was lost in an FNB atm. I was told that the card was cancelled. More than 3 months later (beginning of July 2018) I receive notifications of use of the card at a number of Tolls. I report the incident and was told that the card has been cancelled and hot-listed. This happens on another 4 occasions with me reporting the transactions and then being refunded. Each time, I was promised that the card has been 'hot-listed' and told that this cannot happen again once 'hot-listed. 6 Aug 2018, notifications on my app and via sms of more transactions at the same toll!!! How can a card that was hot-listed a long time ago still be in circulation? What happens if the transactions deplete all the funds in my account (as had happened at end July 2018) when my debit orders are due to go through? This is extremely frustrating as an FNB account holder!!!!
