Discovery - Stay away

Oh my goodness, this situation with Discovery Bank is absolutely driving me up the wall!

Imagine waking up to find an email that reads: "As of November 12, your credit product balance stands at a R 0.56. Please note that a minimum payment of R 0.56 is required by December 5."

This is particularly frustrating considering that I recently closed my account and had previously received a settlement letter. It feels completely absurd to be notified of such a trivial amount after the account was supposed to be closed.
