Nedbak freezes credit card without warning

Nedbank I am once again extremely angry with your lack of service. You have frozen my credit card without warning or any notice period because I haven't used it recently!!! This is disgusting terrible service I am in credit so how dare you cut off access to my own money without adequate warning.??? What if I was in a medical or other emergency and needed my credit card???? I have been trying for the last 24 hours to get this card activated again without success and I am very bitter and angry.

If there are any other banks out there who would take over my accounts and cards who dont treat their customers like numbers and so disgustingly please contact me, I am so, so , so so sick of Nedbank
