Moved my account without permission or consent.

Discovery Credit Card just migrated to Discovery Bank from FNB without my consent. I find this lack of communication awful. The only reason I took a Discovery Credit Card was because it was administered by FNB. As a existing FNB customer this worked great. The Discovery Bank platform is not user friendly. I don't want to bank with them, yet the managed to somehow move my bank account. Dishonest at best.
