Contract application declined for LTE 10 mbps 24 monhts contact

I app**** for a Vodacom contract uncapped LTE at 10mbps for a duration of 24 months as per their black Friday promotion, I have told by your store that I do not qualify hence there is default on my name, I have since asked what default are they talking about, hence i am well aware of my credit score and accounts that I have. No one has been able to give such information to date, all i am getting is a run around. I need an answer today. This is well within my rights as per National Credit Act, I need a written reason explaining why i was declined.
