Building Credit Record

My Son left Matric last year. Started working a few months back. Now he wants to purchase a TV and what does Game tell him. Sorry you don't meet our criteria. How must young people coming out of school have credit record if no one wants to help them get credit. The rules are stupid. How does someone not met your criteria. I would like to know. He gets a good salary. He doesn't pay rent for he lives with us. We give him food etc. He doesn't have any other debt, so how can you deny him credit. I think you should change your rules or maybe state there that you don't help white people anymore. Because his friend has the same problem as he. Please advise on this.
