Ackermans horrible service

Ackermans in Midrand at Boulders shopping center gave me the worst service ever. We stayed in a queue that was not moving more than 40 minutes, when I approached one of the store assistant to complain about this she said there's nothing she can do I must stay on the line because no-one else was complaining. I stayed yet another 30minutes on queue and the line only started moving quicker when they were about to knock-off. I have never felt so disrespected, it was clear that my support was not appreciated and I will make sure that each and every single person I know stops going there because of their disgusting and horrible service.
