Bad service at GAME BOULDERS

I bought K. I. C deep freezer on the 29TH of November 2019(Black Friday). The fridge was out of stock, so I was told they'll call me within 14 days to come and collect. They never called me until I made contact... That's when I was told they'll deliver in 11 January 2020. I never received communication, after calling them on the 13th they told me they still don't have stock. It has been almost 2 months since I bought this product from Game, which is still with them and I'm paying it on installments. I'm getting charged for something that I might not even end up with. HOW IS THIS FAIR????
