Order canceled due to no stock, yet it is still being sold, now at a higher price.

I ordered a Vizuela Full Size Classic Guitar - Blue Sunburst for R 1,440 (Sold by Tropical Music), a week ago, it was meant to be delivered in two days. Today I see online that my order was canceled, and the reason.... out of stock. BUT it is STILL being advertised, with NO indication that it is out of stock, AND the price has now gone up......... I am not impressed and my daughter is very disappointed and heartbroken.
