Discovery is a ****

I no longer want anything to do with Discovery, I even cancelled my medical aid. I tried to closed my account on the 12 September 2025 with the amount of -R169,46 to pay. I didn't pay it then and as account closure request, was closed. Today I paid R166.32 that reflected on my statement and called to request my account to be closed. I am told that I need to pay more money to have my account closed. Currently my account is sitting at R0.32-.
