Call center gives incorrect information

I need to change my banking details so that they reflect my married name and new address. I decided instead of making 2 trips to the bank I will phone their help line and find out what documents I need. <br> I was told all I will need to take is an affidavit from my husband stating that I live with him etc. I will also need an account which has my new physical address on it,when I asked the gentleman on the phone, \What kind of account is acceptable?"( as I know that some accounts are better such as Eskom) he kept thinking i was referring to my type of bank account"
