I'm left with negative balance of R31000

This is the most horrible experience I'm having with Absa, I cancelled/stopped my credit card due to lost in March,before that I hired a car with woodford..

Now in May and June they allowed woodford to do an online purchase transaction of R31000 in my credit card using my old card details and ccv number the card that was canceled yet my credit card account has no funds.. Now I have negative balance of R31000 that I have to pay..

I never gave woodford new card details and absa ***** line consultant are telling me that since I gave my old card details they cam do any transaction as they wish even if it was cancelled...

Now my credit card is on negative R31 000 and I was paying it very well... It funny because other companies such as Netflix and Spotify Absa decline them when they do transactions on a stopped card but woodford went through...

They are telling me that they done with investigation, woodford told them I have a case with them but I neve signed any contract for woodford to deduct that amount in my card, at the same time the same woodford took me to attorneys for a default jusgement on the other side they are doing ******* transactions...

I feel vulnerable and less protected by absa, what is the use of stopping a card if it can still be used, why they allow a company to do an online purchase for such amount yet they account has a balance of less than R500...why it never decline since there was no money..

I'm so stressed and undergoing depression for such treatment I'm receiving from absa and it not for the 1st time... I've been a client with them for so long, I was paying my credit card well in order to buy a car through them as they rejected me last time,but look now my name will be defiled by them...
