ABSA Savannah Centre - Polokwane

My parents visited an ABSA branch in Polokwane today and had to wait outside for almost 2 hours while the bank employees came to fetch people behind them to go into the bank, the question is ABSA now refusing to help white people as my parents were waiting in a queue not so long while other equity people were taken from the back and assisted before them? My mother has said if this is how ABSA is treating their customers she will close all her accounts and this goes for me as well, treating older people like this is unacceptable. I am disappointed in ABSA Savannah for treating people like this!!!!!!
