Bad service

I made an application to finance a car. The application my was declined. Called the bank to find out the reason for rejecting my application and the agent on the phone told me the system says its affordability. I was like how so? Because the bank just financed me for a car in the same prince range as this one last month and that car was settled on Tuesday (2019/03/19). The agent asked that I should give him a moment to check something...after that he got back to me and said that he sees that I had an account, the account was closed on 2019/03/19 and he also do not understand why the system is now declining the application. He told me that he will consult with the credit department and he will get back to me within 30 minutes. I waited for more than 1 hour and he never got back to me. I called the credit department, they said they cannot find anything from their side, I was transferred back to customer care and was transferred back to vehicle finance....then this other lady put me on hold for like 1hr20...I need this to be sorted urgently.
