FnB service for private clients is aweful

Its with sadness I write this complaint cos I really love FNB but the way I have been treated is unexceptable. I am a private client and my private banker been working on my compliant for a week with no resolution in sight. My internet banking is blocked and my cards are inactive so I can't reset my password. I have been a loyal customer for years. Please note that I'm also overseas so I can't pay anything until this is resolved
