Bad disappointing service

Very bad service. I opened a Nedbank cheque account online. The agent that helped me took all my details. I then after a week collected my cards. To my great disappointment my cards were on My surname of 10 years ago. I am Abrahams now but the cards is on September. Now they want to charge me 100r per card to change the surnane. I feel its not my fault why should I pay. I immediately went in the branch and they could not assist me. Should I close the account. I did not even activate or use the cards. Why should I pay for their mistakes. How fair is that. I am thinking of closing the account
