BAD SERVICE

Hi have been phoned by Nedbank after applying for a personal loan. I went through the whole application and was granted a pre approved loan of R106 000.00. The consultant advised me to get to my nearest branch to finish the application. I went to Wonderpark with all the required documents and was helped by Kgopotso. I signed the contract/qoute and all the required documents was faxed through. I was advised the following day that there is something wrong with my payslip. It has been going back and forth for 2 days where i phoned the branch for feedback and no feedback was given. I insisted to speak to the team leader Gift and he advised me know that the loan has been declined. WHAT SERVICE IS THAT??
