Takealot pulled a dirty on me

Hi, I just recently ordered an item off takealot a few days ago. The item I purchased was going on sale and placed the order only to find out a few days later that the order was cancelled. Not by me but by Takealot. According to them they have made an 'inadvertent error' and placed the wrong price on the tv and removed it from the site as soon as they could. I find this unacceptable as I have a confirmation email of my payment made to them and the money was taken from my account. I believe I should get what I’ve paid for whether they've made a mistake on their end or not. This is false advertising. Just the next day for a week they placed the same item on sale again but for a higher price. So they can’t tell me they’ve been ran out of stock because it’s the same supplier and same item that’s was on sale. I want my item no questions ask. This is the first time I’ve received such poor service from Takealot. They’ve already gone ahead and credited me my money back. I want my item I purchased, not my money back!
