Bad Service and delayed response

I sent a request to change my address on 25/10/2017, I sent the proof of bond registration I was told they dont want any doc from FNB, I mean WHY? I work for FNB, I have accounts with FNB when I finally got certified Telkom statement, they said it's not clear, when I resend the same which is not certified but clear they said it's not clear and that is not the only even the financial manager at the Bruma dealer 'Fiolla Jafta' she just ignored me when I asked for a copy of my contract, Pathetic people who work with people but dont give a damn about them.

my address has not been changed by the way
