Question 101: Promotion fees

I just signed up for Tae Kwon Do training. Last belt promotion (yellow belt), I was told they now have new color belt system. There are white, yellow, yellow with orange stripe, orange, orange with green strip and so on. Every color belt now added a stripe which means more tests and more promotion fees. I am upset about this sudden change without any notice; moreover, I am feeling my master of Tae Kwon Do is money orientated. Promotion fees used to be $40 dollars and last month he decided to increase to $60 because of inflation. My perceptions are suggesting something is wrong in my Tae Kwon Do studio. I did not even know there is a fee for belt promotion test. I thought just a monthly fee of 80 dollars for 8 sessions per month.
