Extremely bad service to disabled person

Absa southgate mall have a very poor service to clients. Let me rephrase that here is totally no service at. My wife is wheelchair bound and has been in this Absa branch for the 4 hours with no assistance. Firstly they asked my wife to sit and wait to be assisted but they then left gor an hour before giving her a ticket to be assisted. As far as I know the elderly and the disabled cleints share one fast tract line but not within this branch they get lined up within the same line.
