I want my money

the worst service ever. On the 22 on September i ordered a western digital 120Gb nvme drive for R 561.57 only to be told on the 25th they had nothing in stock from the supplier, and gave me an option to cancel and get a refund. so i asked for the refund. On the 29th i asked what is happening . Then i get a email saying i must supply them with my banking details and proof of purchase, which i did. On the 2nd of october i get an email "Thank you, I have forwarded to our Finance department and they will process your refund via EFT. The soonest they confirm the success of the refund, I will contact you". Still waiting for my money. Im am ****ed off about this and sick of waiting and them using the covid19 for stuff all customer surface
