Fnb ***** case fnb fault

About 2 weeks ago my bank card was ****** and when I tried to stop it on my online banking my card was never linked so I could not stop it the could actually just stop the old cards so the ***** kept on using the card and drawing money that is unacceptable and the ***** line is useless as u can't get through when I got to the bank and my account was empty I was informed that the cards was never linked and we told them the week before when we where there to link it.... ***** case opened new card go to the bank and also find out the new card was Nog linked this is very disappointing service and I would not recommend fnb too anyone as the service is extremely poor and this is unacceptable.
