Fridge not yet Delivered since 21/01/2016

I bought a Hisense fridge on the 21/01/2016 and told me it will arrive after 14 days, i drove with my own petrol to check if the fridge have arrive on the 5/02/2016 and they told me the fridge have not yet arrive it will arrive before Sunday and they will call me and inform me its there before the end of the day on sunday even if they dont get the stock, NO1 called me. i drove there today using my own petrol again and they told me the is a stock that arrive today and my fridge is not on that stock. i have use more than R120 for petrol and my time it keeps on wasted by poor service of your shop. i dont know whether i should take back my refund or you are going to deliver for me because you have wasted my time and money with your empty promise
