I want the boot for that price . But the person must not pay the difference

I went into legit retail in Malmesbury, to purchase boots as they had a special. I took 2 boots and one boot was price at R44.99 when I went to the cashier it was actually R499.00 . The manager then said that the person who did the incorrect pricing should pay in the difference , witch I was very shocked in. I walked out of the shop came back and returned the boot as I feld it was wrong . The area manager Hershell has the same attitude towards this ********* rule that the person who did the mistake should pay for it . She is rude and have no Erea manager skills . If this is how a company treat their staff then people should not purshase by them . No morrall.
