Bank Cards linked incorrectly

On 28/05/2024 I went to the Centurion Mall branch to re-activate my cellphone banking and get a debit card in the meantime. That debit card only worked once and never worked again since. I called the card division for assistance, I have just been informed my cards were linked to the incorrect account. After we clearly discussed everything will be linked to my account ending with 300 this person linked incorrectly and I am not expected to g back to the branch to have this fixed. This is causing huge inconvenience for me because of someone's error, can you please have this fixed.
