No stock for 3 WEEKS? Absolutely unacceptable!

I placed an order on the Telkom website and a sales agent called me back to complete the order for an Honor x9a which was the device I had chose. This was on the 20th of February 2023. It's now the 3rd week that I've been calling in everyday and I've been told that there is no stock of the device. While the help center agents are helpful and quick to pull up my order status, they are unable to tell me when stock of the device will arrive. I understand the whole "first come, first serve" principle and I know that stock will be allocated to people who placed their orders before me. It just seems incredibly ridiculous to me that a big company like Telkom can consistently have no stock for 3 weeks. Shouldn't it be obvious that if the device is consistently selling out, it's in high demand and larger bulk orders need to be placed? I've chosen to cancel my contract with my current service provider and switch over to Telkom, and this is not the start that I was hoping for. Utterly disappointed.
