Home Loan turned down versus client history

I had been a client with FNB for the last 10 years, have a personal & business account, had a Bond, fully repaid and closed. Now when I app**** for a new bond for a property I am buying it is being denied. Nothing in my circumstances had changed, still the same client, business owner who paid a bond in full with FNB, still same accounts, except my new bond application is even less than what my previous bond had been, my business is in a much better financial position. I have taken my issue up with my FNB business manager - she/he seems less interested to mediate my issue with the Home loan department. There is little to understand here for me, excellent profile with FNB (my home bank) and yet they decide to not approve a home loan. There seem to be no willingness to act upon my client history. This ordeal and poor reach out make me think it is time for a change, a change in banking service. One would like to think and hope that your good track record count for something, but seemingly that is only the case when you receive yet another call for another FNB service /add on that they want to sell.
