Application approved but advised it was declined

I was misled and **** to by a Sales person from the Fourways branch by the name of Leon. My application was approved but "conditionally approved". I called MTN Head office to obtain more information about my partial approval, since Leon from MTN Fourways said it was because of the credit limit, wanting to verify the increase of credit limit, since I have done adjustments to my credit. The vetting Department advised that, if its approved on condition it means that the consultant either have to do a manual credit limit review or rather an upfront payment, for the mere fact that it was approved not declined. Then Leon called me today on the 18th Jan 2024 to tell me that my application was unsuccessful due to affordability, he did not offer me an alternative or further advise on that. Yet I told him that I paid R13000 on one of my debts. I find this bizarre. I have a track of emails stating that it was approved today 18.01.2024, how does it move from being approved to being declined? I need someone to intervene and advise me about this level of service I have received, and constantly having to call him for feedback ever since I did an application with him.
