FNB useless Private Bankers,Also FNB useless bank

We shall use this platform since FNB only recognizes communication from Hello Peter..Please tell the useless banker Isabel Mkhize and her colleague Nwabisa Zilwa who never picks up her phone..I will not chase her to return my calls,I've been calling her from last week Monday,not even a single call was returned by her...All empty promises..Dont ever think you doing me a favor this is business and it should be treated as such..
