Interest rates not offered to clients on personal loans but advertised and published by Nedbank

I had taken out a nedbank loan a first after a long time with no previous or other loans. I have an excellent credit scoring and have all of my financial commitments only with Nedbank. At the point of taking this PL which was in March 2019 I was never offered the 10% interst rate or a really good rate depaite the above mentioned facts. Yet Nedbank advertises that your PL with a possible interest rate of 10%. I want to know and understand why was I not elgible at that time for a good interest rate. From the liitle I was told by your contact centre the amount taken does not contribute and the major aspects taken into consideration is my credit score and monthly committments. I have maintained all my Financial committments in an excellent manner and I am not over committed. Is Nedbank doing false advertising or are the consultants not offering the product to the client as they should. I need this to be investigated and need to know what is the truth to this. I have also been a Nedbank client for over 12 years now.
