pricing given by staff

On the 31 Desember, myself my husband went into musica vaal mall when we looked at series vikings season 2 and 3. I then asked the employee Themba if the 2 series I took was also 2 for 300. He said to me all the series is on special for 2 for 300. I then asked again are you sure because I don't want to go to the till and then it's wrong he said to me he is sure it is 2 for 300. When getting to the till the cashier said it amount is 500. I then asked for manager who is called Lebohang he then said to me that it's not on special and that if he wants to overwrite the price the system would not allow it I then said to him that it's not my mistake it's the mistake of the staff member Themba. The manager didn't even look at me anymore he just ignored me I then asked for their names and had to asked for the second time. I always buy my series in musica in that store but think this was the worst service I've ever got and for sure will not leave this here. According to CPA it says that if a price is wrong it should be free. But I just wanted to get it for the price Themba said it would be.
