HI-Fi Corporation: worst service ever.

I have had the worst experience with the on-line site for Hi-fi corp. I purchased a chest freezer which was on special for black Friday. My purchase was done on the 28th of November. I sold my second fridge in the week that followed. Today is the 18th of december and still have not received any delivery. I had to call them 7 times and after the 4 call I was told I should lay a complaint then head offices will contact me to resolve the issue. Nobody called me back and only after calling numerous times I found out they dont have stock. Instead of letting the client know I spend hours on the line and the issue is still not resolve. It is Christmas next week and I need my chest freezer but nobody cares and the took my money. Why cant they just offer me an alternative or a refund. Hi Fi Corp worst service I have ever had. Ps I requested an urgent call back from manager yesterday and again nobody called.
