Band banker

I received a sms from Nedbank than i need to swop my debit card for a new chip and pin card to increase the security of my debit card. On arriving at the bank i asked Mornay at the counter when the new card will be active. He answered that my card will work even before i left the bank. On leaving the bank I tried to with withdraw money at the ATM and the card did not work. On returning to the bank and i spoke to Liezl who works Next to Mornay as he was busy and she informed me that they have been having problems with the new cards since last week Friday. I feel that this is unacceptable. I asked if my card will work and he assured me it will. They wanted me to with draw cash inside the branch as this will work. But the bank charges are sky high with cash withdrawals in branch. But don't worry we will refund the bank charges. So now i have to fight and wait to get my bank charges back because one person is ***********? This is unacceptable i asked specifically that the card will work. I am a proud Nebank supporter but this is unacceptable.
