Bad Serve and false email confirmations on Online orders

I ordered a food blender online on the 19th of January 2018 with the company, paid for it and got an email confirming my order with estimated delivery of 5 - 10. On the 25th I got an e-mail confirming my order that it was delivered and complete yet I NEVER received anything. Called the call centre they sent me to their courier company to do the enquiry myself. Only to find that the courier company never received that order from Hifi. 2 days later i called to tell them i still haven't received my order. They logged a complain sent me an email with a reference of my complain. Promised to get back to me within 24 hours nothing happened. On the 31st got a call from the lady by Jabu and she asked me if I received my order I told her that's why I logged a complain. I haven't received an order that I paid for long ago. She said she will call me after 5 minutes. Today it's the 01st of Feb still haven't received my order, no call from Jabu, I called Jabulani Mall spoke to Tseki only to find out that person is on leave today and I will have to wait for her to come back. And she can't promise to call me back coz she's busy with other customers! I then Called the call centre they told me they received my complain and waiting for head office to confirm if they should send my order while they do the investigation. Really I've ordered more than 2 times from other companies online and I've received my orders. Can Hifi Cooperation pull up their service. Especially on online orders coz you pay before you even receive your order.???
