Terrible customer service

I phoned in to get information on an item on my latest credit card account. After being transferred to 4 different people who all asked security questions I was told that they didn’t know what the irem was about. For me to get them to investigate they would have to block access to the credit card and give me a case number. This whole procedure took about 30 minutes on the phone. We have been with Standard Bank for about 50 years and their assistance gets worse daily.
