Unable to downgrade my account

Upgrading my account to Private Clients took me less than 2 minutes; however, it takes over a month to downgrade the account. I'm not using my account actively now, so I decided to downgrade to the cheapest option (Easy). As easy as this sounds, I've actually been struggling to downgrade my account for over a month now (even after 3 branch visits, a few calls to the call center and 2 complaints filed). Apparently, the system at the branch doesn't allow a downgrade to Easy. I'll escalate with the Ombudsman as soon as I can as per their procedure. FNB is a terrible bank with unfair practices. It was a mistake opening an account with them in the first place.
