Frustrating service

Really fed up with the service from Nedbank. I have been banking with them for 22 years and actually worked there for 20 years. They have made one mistake after the next my account and my husband and the most recent (today) is that our cards are restricted, and they need a whole lot of forms filled in as we it's a new onboarding. Highly frustrating systems, process and staff. I need someone senior to call me to resolve this.
