Bond declined but approved by opposition

I am a loyal client of Nedbank with a very good credit history and credit score. I find myself in a very difficult situation as I have app**** for a bond via my bond originator. Nedbank declined my application due to affordability! How can it be?? I am currently paying our monthly rent and the full municipal account of the house we rent - doesn’t that mean anything?? I am self employed with an established business with a stable income, so the bond originator try to apply through my business as well. Until now, I haven’t even received an answer!? The only bank which is willing giving me a bond is not even Nedbank! I’m thinking of moving my finances to this particular bank as Nedbank doesn’t satisfy my needs! This is totally unacceptable! My private banker Alma at Cape Gate branch haven’t even contacted me once to discuss the application with me!! Poor administration and service! Very disappointing!!
