Disputed Credit score

App**** for a full banking suit, got declined, credit decline letter reflected different values for income and expenses than what was entered in the app and feedback was that I have a low credit score from Experian. I paid for a credit score from Transunion, and the score is Excellent. Disputed the decline multiples times and also provided the Transunion credit score as proof via email to Discovery credit, no response. Pathetic service.
