I have a TV almost a month ago that is still not delivered and no commitment

I have bought a TV set from Dion Wired Woodmead on the 11th October 2017, 2 TVs were supposed to be delivered within 3 days but only one TV set was delivered and to date the other TV set is still not delivered. Nkosana, the sales man did everything in his power to an extent that he also got frustrated with LG not delivering the TV and not even taking any responsibility to commit an alternative delivery date. With exception to him, the rest of the DionWired Woodmead business is extremely pathetic and I wonder how come customers are so ill-treated in a disrespectful manner. Even the store manager has a "I don't care" attitude. The fact that they don't even bother to provide update baffles me to why are they still in business, there's is just something terribly wrong and good sales people like Nkosana who earn on commissions are really compromised because their customers would never go back to that store, one would think that such a reputable brand should be much better of in terms of customer relations but the truth is it's all in the marketing, the service is history and people should be wary how and who they spend their money on. Clearly not Dion Wired Woodmead!
