Applied for Citi Diamond Preferred Credit Card. Got approved. 
Was surprised to see being assigned the highest APR possible, because my credit is excellent ( XXXX, XXXX, normal range is XXXX -XXXX ). Called Citi to inquire why the highest APR was allocated?. Also, inquired what was the formula and what credit score was required to get the lowest APR. XXXX nor supervisor could answer. Indicated there is nobody in the whole company that knows how APR is calculated. 

This is both false and deceptive, because Citi represents that the APR is based on your credit scores. However, they are - either uniformly assigning highest APR regardless of your credit score OR using discriminatory ( racial, nationality, sex, etc. ) criteria to assign highest APR 's to certain groups regardless of credit scores.
