SHOCKING SERVICE AND NO DELIVERY OF ITEM I PAID FOR

I will never spend money at DionWired again! My husband and I went into Dion Wired Cavendish last week Thursday to purchase the Samsung TV bundle with the sound bar. The guy was very helpful however only had the display unit for us, he then called Niyaaz from Canal Walk who had 1 set left and promised to keep it. He called us a few minuted later saying he sold the TV and was looking for another one for us, we called him twice to follow up and never heard from him again! We got home and I immediately went online to buy the deal, as soon as the confirmation came through I emailed back saying that we are NOT home during the day so confirmation on delivery was required, I dealt with Cedric and confirmed on email 3 times that we needed confirmation on time. I then received a call at 13h16 yesterday from the courier saying he was outside my front door and there was nobody home, there were NO special instructions to call us. I then rushed home to see that NO SOUNDBAR WAS DELIVERED! WE GOT THE DEAL BECAUSE OF THE SOUNDBAR!!! I immediately called the call centre, the person that helped me confirmed that it was being escalated and that he would cc me into his email, he never did. When I got back to the office, I emailed websupport, I STILL HAVE NOT RECEIVED A REPLY! I have sent three emails and called another support person today and all she could help me with was to say that is had been escalated and was pretty sure someone would get back to me. All we want is our soundbar we paid for, is this really the way you guys do business???
