Rude customer services

Mac donald in Wynberg has the worse extremely bad and pathetic customer service. It seems like they get paid to be rude with their customers and they know even if you complain Mac Donald's does not do anything about your complain. It's really sad this is not the first complain nor the second complain nothing gets done they don't even come back to a person I have made a decision I will never ever go to Mac Donald's again their service is pathetic they give you a wrong order don't even api8, they speak very rude to you that is no problem from the cashier to their supervisor. Mac Donald's in Wynberg in Cape Town should be closed for they don't value their customers
