Worst customer servece ever - HiFi Corporation

I've placed an order for a sewing machine on 4 Aug 2020 and made an EFT payment on the order site. The ad says 2 to 5 working days delivery. I received a confirmation email with the order number, delivery address and all other information. There is also a "track my order" option. I tried to track my order but no information came up. I then used the chat option and was told they can't track a order that's standing still. After 2 days I went through the same process. The chat option suggested I leave a message with my email address as the agents are very busy. I've done that but never received any email or communication. On 13 Aug 2020 I've once again went through the same thing. On the chat I spoke to Stewart who told me he lodged a complaint on my behalf. I asked if they will come back to me, he rep**** "yes". I asked him for the email address which he gave to me. I've also sent a complaint, but till date - 16 Aug - I have not received anything. Not any communication, no email. The time span have been much more than 5 days and I still don't know where my order is. This is the worst on-line order experience I've ever had. Thany you HiFi corporation for the worse customer service ever!
