Appalling service from credit card division

I'm trying to close my credit card. Sent the required mail through on Wednesday, got phoned this morning. Only to be put through to a call centre where i was on hold for 15 minutes, before someone picked up I explained what I wanted and then got put through again - this time to the retentions division. I couldn't quite make out what I was meant to do there due to the baby screaming in the background, but it didnt really matter as when I was transferred AGAIN I got cut off. What a circus. I wish the bank would streamline their processes so that you don't have to jump through hoops and get transferred multiple times until you eventually find someone who can help you. Calling Standard Bank for assistance is like entering a lucky draw.
