Incorrect pricing of item

I went on takealot.com's website last week Friday, 03/08/2018, and was browsing through gaming category by price low to high and I happen to come accross a gaming mouse which was marked for R109. At first I thought maybe it was a component and I also thought maybe I saw incoreectly. It was those unboxed deals so I checked the price and read the description and confirmed it was a mouse. I added it to my cart and the price is around R1040 if I am not mistaken. So I phoned takealot.com and was told to email a screenshot and the link or description of the item. They confirmed the item was correct and said that they will get back to me. No one has contacted me so on Wednesday I phoned and was told that the item is being queried with the supplier. Today I get an email stating that they are still checking up with the supplier. How long does it take to confirm a price for an item? Why does the customer have to be inconvinienced if there is an error with the price? This is very unprofessional from a big supplier like takealot.com. I always purchase from takealot.com and never had such a bad experience
