Incorrectly advertised items and lack of customer service

Checkers Riviona Village Sandton.Did have stock on advertised specials yet they have a cheek to cheat customer's and even place the placard on the incorrect item.Ingrt.to the teller and spend 20 min trying to resolve this.I eventually gave up and left.I even had to on 4 occasions walk to the ilse as the managers and supervisors didn't know where the products are located in their own store.What a waste of time.
