Interest rate ****!!!!

I app**** for a credit card yesterday and I was given a quote with a ridiculous interest of 22% wherein the maximum interest rate they can charge is 22.25%. I have a bond and car loan with Standard Bank and the interest rates I have been offered are 11.25% and 11% respectively. I have a good credit score and my expenses are not high. What justifies the extreme interest rate? From 11.25% to 22%? How is this possible? Such a high interest rate indicates that I am a high credit risk.

When I informed the sales person that assisted with the quote, I asked that he escalate my query and he said he does not know who he should escalate to. This is ridiculous!
