Zando - Charges for Express Delivery and 5 days later still no delivery or news from them.....

ORDER NUMBER: *** ORDER DATE: 5 Dec 2019 Placed an order on the 05 Dec 2019 and paid an additional R60 for express delivery. Note that full payment was made at checkout. I contacted Zando on the 6th to find out what was happening, the consultant advised that she could see on my profile that I paid for express delivery, however told me that due to black friday, Zando has been inundated with deliveries, apologized and said that she will email me feedback. To date no feedback from Zando. Since Friday I have emailed Zando as well as messaged them on their Facebook Messenger and no response.
