Vodacom Extremely Unhelpful

So just recently I made a contract with vodacom online for new phone. I get told that it will be on a new number, though I was never asked if I wanted one, which I do not. So I ask if I cannot rather use my old number. The first person tells me it will not be possible. I query at a physical store and get told I have to contact Vodacom Online and ask them to cancel the contract first and redo the process. So I try for 2 days trying to get hold of an actual person instead of their Tobi AI, and I do. But the person, Steven Pennefather, ends the chat on me without giving advice. Twice. This morning I'm told my phone has been sent out. And I after trying for a few more hours, I finally get hold of another actual person, who tells me if I had to cancel now, I would get declined if I tried to make a new contract. I'm severely disappointed in the lack of help Vodacom had and the services they provided.
