HiFi Corp, no delivery, no communication, no idea when I'll get my money back.

I've been waiting 10 days for my Online Order for a Defy 94lt Bar Fridge Metallic B4802M, placed and paid for in full via credit card R1,499.00 in full on Monday 02 December 2019 before 09:00 am Site said 2 - 5 days delivery. They called and promised delivery on Monday 9 December. I took a days' leave to accept delivery, and waited for the call that they said I would receive an hour before delivery, but nothing. As yet, on 12 December 2019 at 14:00 there is still no delivery or promise of one. I've emailed, used the 'talk to us' chat function on their site and tried to call numerous times, each time just holding on until I couldn't anymore. Last one was 8 minutes. They offer absolutely no help or answers when I sent an email to follow up, and don't even acknowledge my emails. The support chat function for assistance was also unsuccessful. Chatted to Deon who simply wasn't able to assist because "he doesn't have access to the warehouse system" so he doesn't know when I'll get my order. Checking the order online, it just says "Order placed successfully" and "payment received". After 10 days the order still hasn't even reached the "order picked and reserved" status. Keep in mind, when placing the order, the system showed they had stock. I know this because the microwave I also tried to buy said "no stock". I thus cancelled my order with immediate effect and request an immediate and full refund of the amount paid R1499.00 that I paid back into my credit card. I did this via email, the "contact us" page that gives a "cancel order" option and via the "talk to us" chat function with Chelsea. Chelsea advised "If you would like to cancel your order, please send an email to ***, making your order number the subject line .Once the request is received, your refund will be processed in 7-10 working days." I responded with "Thanks Chelsea, but I suggest that the refund be sooner, as you've already been sitting with my money for 10 days, adding another 10 will result in 20 days of interest owed by Hifi Corp to myself." Chelsea rep**** "Unfortunately, that is the only time frame I can advise" I can't help but wonder how many other people are sitting with this problem. Money out of your credit card, no delivery or promise of one, and now they play the 7-10 days for a refund card when they had my money with immediate effect. It was the first time and the last time that I will every buy online (or in person) from Hifi Corp again.
