Refund

I ordered a defy built in set and a kettle on 30 June 2020. Till today I haven't received nothing. I call their online department and enquired about my order and I was first told that due to covid 19 it will take longer to deliver, which I understood. After about 18 days I called again and I was told the kettle is sold out and will receive a refund. On the 20th July I called to enquire about when will I receive my stove and I was also told that it's also out of stock and I'll receive my entire refund and it will take 3-5 working days after a long wait and battling with their call center I finally received my refund which was only R299 for the kettle, I haven't received the refund for the stove and the delivery fee which is R3849. I'm drained cos when you call the call center they always promise to get back to me ,which they never do. I just want my full refund back and I won't wait for another 3-5 days .I need that money today. Order number is ***.
