Loot.co.za failed delivery

I placed an order for an external hard drive on 10 July 2020, with a promise of delivery on or before 16 July. On 16 July Loot sent me an email stating that the product was out of stock and they offered me a R150 voucher, or my money back. I decided to make use of the voucher and placed another order for the same type of external hard drive, with a promise of delivery on or before 24 July. On Saturday, 25 July I made an enquiry via Messenger, after I have learned that they don't answer their phones. They responded the same day with a promise that they will look into the matter. On Monday, 27 July I received the following message: "Apologies for the delayed response - unfortunately, we have not yet received an updated ETA from our suppliers. As soon as we receive feedback, we will let you know." To date (30 July) I have not received any excuse nor an explanation from them. I would like my order to be delivered or a full repayment back into my bank account, but I have no idea where I stand with them.... I am worried that Loot will become insolvent and I will loose my money. The referenced order number is XFMV-283-B990
