Unacceptable Susupension of my Credit Card

Today I tried to make an international payment, only to be informed that there was a problem with my card. Shortly thereafter I got a SMS informing me that my card had been suspended for my protection!!! I was told to contact 010 - ***, what a waste of time that was, no one answers that number. I then contacted my private banker Nolwazi and Nkosi, who both undertook to get back to me, by the end of business today, 22 July, as to why this happened. No surprises, no one has bothered to get back to me. Clearly Standard Bank is behind other Banks, certainly Nedbank, where under these circumstances, I get an sms asking me to confirm the payment.
