Hot card

My online banking access was stopped without warning this morning. When I phoned the suggested customer care number about this, they passed me on to the ***** line who passed me on to the credit card ***** line who them cut me off. I phoned the ***** line again only to be told that the card had been stopped but there was no info on why and I was told I had to go into a bank branch to resolve this. No one from Standard bank contacted me about this and no reason has been given for this. I am now waiting in a long queue at the branch wasting my time as no one at customer care phone lines was able to assist. I call it passing the buck and have been totally inconvenienced by this.
