False advertising

I opened an 4me savings account for my 12 year old son at N edbank this week. They were very helpful and explained how the account works. Outside the bank I let my son deposit R50 at the ATM just to show how it works, and Thandi explained that you will not be charged bank cost for the first R500 cash deposit. When I transfered some more money the next day, I saw they charged him for the deposit. I checked the brochure and there in writing it says \first R500 cash deposit free per month "So I phoned the 086 number on the brochure"
