Callcentre agents have no insite neither do their supervisors

I have been a loyal discovery member on and off for several years. I recently my changed banking account. I have since then had the worst experience with the Discovery Callcentre. I have since November month been going back and forth, paying money, having it refunded paying it again. I even spoke to a supervisor who promised to call me back and have the matter resolved. That was two months ago. Now I have to sign a reinstatement document, after which I have to wait two months before I can use my medical aid. I believe this to be unfair as I have been trying to resolve this proactively for several months

The Callcentre are not interested in engaging in anything outside of what seems to be scripted on their screens and this entire process is very annoying
