Incorrect Information to client

During the course of this week i realized that my new FNB cheque card would be arriving soon (as FNB stated) I also decided to open my daughter a youth acc at the same time , i was to told to have all the relevant FICA docs , i then realized that my address has not been changed to my current one , i called and emailed FNB and asked for the relevant docs , i informed them that i am living with my unemployed father in a state/subsidized home and he himself has no retail accounts as do I.I sent through his proof of address when i was told AFTER sending it would not be applicable , i sent through a sworn affidavit and they still would not accept it.How are we supposed to bank with no retail accounts as proof of residence , all i wanted was to have my residential address changed.Every other bank accepts an affidavit why not FNB...To date FNB has NOT gotten back to me with a resolution...I will be contacting the banking OMbudsman
