Cancelled my card BEFORE I collected the new one!

My account was changed and new card delivered to my branch. I have been out of the province for work and was unable to collect my new card! To my disgust, while trying to pay for formula for my baby, my card was declined. On querying with Nedbank I was informed that that card had been cancelled and that I needed to collect my new card. I explained that I was only able to get to a bank on Saturday due to my work load and their business hours and what was I supposed to do until then?? I have been with this bank for more than 20 years, since I was a child and NEVER have they cancelled my existing card until I collected my new card.<br> <br> I am infuriated and very disappointed!!!
