False Promise to Deliver AND Terrible Customer Care Service

I ordered a Sinotec Television and a HDMI cable from Hifi Corp on the 24th of November at 00:30. Now I know I ordered it on Black Friday so many complications can occur and I also know that the goods take 10-15 days to deliver but I have been contacted three times now to tell me my order is being delivered on that day ONLY for the delivery to never occur and for the people who are in customer care to tell me they don't know what's going on with my order. What is that supposed to mean? Yesterday I was told they don't actually know where my goods are. I was told they will phone me back today which they never did. I was then told to "practice some patience" what type of person who is supposed to help someone says that to them? I would be patient if I didn't have to rush home from work for three days to collect my tv which was supposed to be delivered but in fact wasn't. They also tell me to contact Mastercare who will deliver my items, but mastercares number that was given DOESNT EXSIST??? I'm losing my patience and don't appreciate the lack of knowledge by the customer care people as well as the lack of communication between Hifi Corp and the Delivery company... how can nobody know where my parcel is and how can I get sms's and emails and even phone calls saying my package will be delivered on the day THREE TIMES only to be let down and for nobody to know where it is???

Useless! If I had known I would of bought my items from somewhere else! And I will never recommend Hifi Corp to anyone! This is going to go all over social media if it isn't resolved
