STILL waiting for phone after 3 weeks...VERY POOR VODACOM

I was approved for a contract with Vodacom online for the iphone 8 on the 7th February and was told it would take 3 to 7 working days. They asked me what colour I wanted and I actually wanted the white or gold but I was told they don't have those in stoke so I asked "what do you have in stock" They said space grey and I said "okay that's fine" so after 3 days I called to ask when my phone would be delivered and I was informed they are out of stock which no one told me, they told me they have stock of the space grey.

It is now 3 weeks later and I am still waiting and when I call into the customer care I don't get any assistant I just get told out of stock and I must wait. No one can even tell me when they are getting stock.

This is unacceptable
