Unclear on Regulatory Regulations

My friend has requested to open a savings account from your company. Caitlin Easton, has now twice refused to assist my friend. What are the regulations concerning opening a bank account for an expat not living in South Africa? Why do you refuse assistance? Your mission statement reads as follows: "Our mission is to help people spend smarter, manage debt better, and save more so they achieve a brighter financial future." This is exactly what my friend wants to do! Is there a reason your company does not help expats? Caitlin is not showing any regard for Discovery Bank's mission statement. What a shock to hear how she treated my friend. Also refusing to supply regulatory reasons that are valid, clear, and understandable to the novice out there. Poor work Discovery, I'm disappointed.
