False adverti*****t

I wanted to buy a laptop (Asus f550). It costs R11999 and on the tag is said i can pay R567 x36 months. So i said id like to take the payment option. I had to apply for a rcs card and besides the horrible service i ended up only getting a max credit of 3000 rand. I then asked why i couldnt take it on the payment option on the price tag but i was told it wasnt available any more. So they were false advertising. Plus the sales person could have just told me that it wasnt available from the beginning.
