Where is my laptop, Incredible Connection?

Two weeks ago, on 18 September 2021, I bought an Asus X515 laptop from Incredible Connection at Eikestad Mall, Stellenbosch. On the advice of the sales assistant, I chose to collect the laptop from the Eikestad Mall branch, once delivered. The official delivery time estimate was 3 to 6 business days.

Today, two weeks later, I am still waiting for delivery of the laptop. After numerous phone calls and a personal visit to the branch, I have only excuses and no sign of the laptop. I have been told that I cannot have a tracking number, since I have chosen to collect from the shop. Extraordinary. Every customer is entitled to a tracking number for a product purchased for delivery. I have been told that Incredible Connection has switched couriers and the new delivery time estimate is now up to 14 business days. This is out of the blue, without prior notification to me - a breach of agreement and good faith. My sister, for whom I have bought the laptop, needs the machine to start her new business. She is loosing in the process by this delay - potential damages if this situation continues. I am not impressed with Incredible Connection. In fact, I shall not buy anything for delivery there every again.
