Bad Customer Services

My husband went to the Graanendal branch and bought Flora 500g on the 14/10/2020. The label on the shelf stated R59,99 for 1kg Flora ProActive. He bought 2 500g but paid R59,99 each(not what was advertised) He only noticed the price at home and went back the next day/ Where as the supervisor told him Head Office must investigate this as it is wrong and that they will get in contact with him. Big joke as its a week later and nobody phoned. What excellent service is that?? We all know the customer policies and that`s not what was suppose to happen. Clearly the staff there is not up to standard.
