Unfair treatment

I was told by Ackermans tellers at Centurion Mall when I got to the till point that customers are no longer allowed to laybuy on-sale items. Considering the economic conditions in South African at the moments how are we supposed to afford to buy any clothes. This new rule that the branch in Centurion suddenly have is very discriminatory against those low income earners who cant afford to make large purchases all at once, and actually rely on marked down items. Some of us rely on lay buy to be able to afford to buy our children new clothes, even better if you find something at a lower price than expected or finding items on sale. If Ackermans does not was us to Laybuy items on sale then they should s**** the whole idea of lay buy. Why do you have this option if you will set rules that don't work for your customers. Very disappointing. And why are they not telling all customers in advance instead of finding out at the till and looking like some kind of an idiot.
