UPGRADE ONLINE "NO STOCK FOR WEEKS"

Ridiculous service, I have upgraded one of my 4 contracts held with Vodacom over 3 weeks ago for an online exclusive deal. I understand that the upgrade states 2 to 3 weeks delayed delivery on the product due to it not being in stock. After calling the contact centers many times and been transferred between 5 to 10 departments each time there still isn't any progress. Nobody can tell me when, how or who orders the stock. Not a single person assisting knows anything. The product (MSI Katana 17 i9 16GB/1TB SSD 17.3-inch Gaming Laptop) which is still being advertised on their website under "Laptop Deals". Why do you sell a product that you don't have a clue if you have stock or when you will be getting stock. I'm glad that 3 of the 4 contract will be in their ending period very soon and if Vodacom can't go the extra mile for a costumer who have been with them for more than 2 decades I feel the need to move my business elsewhere...
