Review Personal Loan Application Processing Time

I applied for a personal loan at one of the branch in the Western Division and I was told that it would take 3 working days to process everything. And to my surprise it nearly took them 5 working days to process the application. And I am still waiting for the result. I already have an account in the company but I don't know why it took them so long to process the loan from 3 to 5 working days.Thank you. Please be better up in future.
