Deeply disappointing and disgusting service from Vodacom

I have honestly never been more disappointed in a company than I am right now. I placed an order for the Samsung Note 10 plus online exclusive deal, order is confirmed and I am advised that the device is on backorder and will be delivered within 4 weeks. Today I get notice from Vodacom that the order is canceled due to the device being discontinued, according to the representative I spoke to, Vodacom has been aware of this for the past 2 weeks. If the company is aware of this for 2 weeks already, why was the deal still available on the website, why did the consultant complete my order? When I requested to speak to a manager, I was requested to call back at 14:00, I call back at 14:00 and get informed that the manager has gone home and there's nobody else that can assist. I'm trying to get assistance from the representative I'm talking to about the way forward and the representative drops the call while I'm still talking.
