Oil Price. False advertising.

Very disappointed. Game Baywest Port Elizabeth. Went to buy Car Oil and price on Bar code R189.00 so purchased one with other shopping. Came home husband uses oil that evening We check slips oil was R479.00. Went back to complain. Oil still in the same place. Reply to my complaint. Not sure why it was put with the other oil. If it was one bottle I would think ok someone put it there. But not a whole batch. Game false advertising and with the Covid Virus people are shopping quick. Game u are *****ing our money. False advertising not happy.
