They only pick up the phone when you want to open new credit but not when you want to close existing credit

Funny how opening credit is always easy but when it’s time to close it, you’re sent from pillar to post. I’ve been trying to call Standard Bank credit card division since yesterday to close my credit card account but they are not picking up the phone. I’ve probably spent 2hrs and wasted my damn airtime/minutes trying to talk to someone. Only the other agents pick up but NOT credit card closure/retention department. One even said I should go to a branch, they would be able to assist me, I just came from the branch, they couldn’t do anything for me either. What a waste of my time and worst of all I’m working night shift this week so I wasted sleep for absolutely nothing.
