Transections on a cancelled credit card

On 16 Feb 2023 I cancelled my lost credit card on the app 10min within losing it. To my surprise from 28 Feb 2023, I started getting toll gate transections notifications on the cancelled credit card. I have called FNB about 15 times in the past 4 weeks reporting every transection that went off the cancelled credit card. I was informed that the card is on the hotlist meaning there will be no transection going through it. On top of that I was told that all transections will be reversed by 22 March but instead there are more transections going off the card. I have a total of 23 transections made on the cancelled card amounting to R4461.00 and still counting.

FNB has failed dismally to resolve this problem!
