Rejected Vodacom contract application (***5)

I have recently made an application for a new contract and it was rejected without no explanation or whatsoever, there was no explanation or whatsoever or any criteria discussed with me on how and why the application was rejected? I would like my application to be reviewed and with better explanation on what criteria is followed when rejecting/approving contracts application form. Surely the consultant should be trained enough to give explanation on the application process?
