Wesbank shocking existing client service

I have had car finance with Wesbank for over 10 years. I am applying for finance for a new car to be told I cannot get the finance as I am currently renting out my house and they cannot pick up the payments from my tenants , needless to say it is on my bank statements as well as the lease agreement I have sent. It is sad when this platform has to be used to assist , when incompetence comes into play and poor customer care , considering I have been apart of Wesbank and FNB for more than 10 years.I need the finance sorted , Mark White Nissan are trying there best however Wesbank are showing poor form.Shocking service to an existing client.
