VROT MEAT AT MAKRO GERMISTON

I am disgusted in the meat of Makro Germiston, I bought Pork Sausages from Makro Germiston on the 27/05/2018 and when I opened it the meat was off there were even nice black sausages in between. when I looked at the sticker the sell by date was 26/5/2018? so the meat was old and expired. when I phoned in to speak to the manager I was transferred from pilar to post and I have to bring in my slip with the "off" meat to the store? so why must I bring vrot meat to the store if its pork? does Makro expect me to drive around with vrot meat in my car? I am highly disgusted and never experienced such bad quality of meat at Makro
