Incorrect price on item

There was a marked down item that showed R374,90 and the original price was R4999. I told the assistant that I wanted to purchase it and confirmed the price, she then burst out laughing and said no it was a mistake. I told her that I wanted to see the manager. The manager told me that it was an error and she can sell it to me at 50% off... I told her that as per the consumer protection act it needs to be sold as what it’s displayed as. Long story short- @home willowbridge your staff is unprofessional and the service is appalling.
