Nedbank Mall of Africa shocking Service/Nedbank Duplicate transactions

I would like to lay two complaints against Nedbank Mall of Africa. One for falsely saying a card had been blocked and two for duplicate transactions.

On the 15 of July 2021, I went to the branch to replace my card as my phone was ****** and the card as well. The lady assured me that she had blocked the ****** card and the new one has been activated. Fast forward to today, I logged on to my app and I find that the card is still active and that I now have two cards active. I then blocked it myself on the app. This meant that from the 15th of July 2021 - 26th July 2021 my money was at risk should have the ******* decided to tap my card.

Also in the same breath, Nedbank conducted a duplicate transaction on my account. On Saturday 24th July 2021 , I processed a payment for rent; the payment then went to Scheduled payments and informed me it would be released today (26th July 2021). Sunday morning the same transaction went off and my balance showed a double transaction.

I went to the branch, I asked the teller and the teller said he doesn't know how it happened. I felt that answer was unknowledgeable and negligent. He went on to say if I know the individual the money went to I should contact them. Suddenly it is now my responsibility to account for Nedbank's technical glitches.

This amount is still a pending debit it hasn''t even reached the landlord. How sure am I that it is even going to reach them? Or it will stay hanging in the air.

After this it makes anxious to be a Nedbank client and after being a client for over 10 years this is shocking
