Worst Delivery Service from Hifi Corp!

I've purchased a side-by-side fridge through the Hifi Corp online portal on the 27th of November 2019. The payment was made and the status on my Hifi Corp profile said payment received. Delivery would commence within 2 - 5 working days. So according to my calculations the delivery was supposed to be made latest on the 04th of December 2019. I tried the "track my order" option, but only the one dot saying payment received was ticked. Even after the 5th day. I then tried to call (***) and follow up, and after an answering machine answers the phone, I choose option 3 which is for online orders. The phone rings a few times, and then the call drops. I've even tried the 2 close-by Hifi Corp stores (Oakdene & Eastgate) to try and see if they perhaps can assist me by tracking my order. I was told that they (the stores) were blocked by Head Office and they can't help tracking my order. On Wednesday the 4th of December 2019 I received a call from *** and the gentleman said he was calling from Hifi Corp online delivery division, and he stated that the delivery would take place on the next working day anytime between 8am and 7pm which was yesterday the 05th of December 2019. I took off from work to assure that I would be home when they arrive. They NEVER came, I waited like a fool. They never attempted to call and reschedule or update me. After numerous attempts to call Hifi Corp Head Office i am still no wiser as to when my delivery would take place!!!!! This is the worst service ever. I've sitting without a fridge for the past week!
