no further information on reason for decline loan

Apl**** for a loan through absa, I then waited 5 days before a consultant could phone me back and guide me through the process. Then there after my loan was declined due to bad credit rating. I requested further information as to who gave me the rating and they couldn't give it to me. I want to know as to why I got the rating as I always had good credit with both african bank and absa. Your help will be appreciated. Regards wesley timms
