Very bad service from Elite Mobile and being **** to by Elite Mobile.

I was called last week (2019-11-15) by an Elite Mobile agent and I upgraded my contract for a specific phone and colour while on the phone with Elite Mobile. The agent confirmed the colour was available so i agreed to the Upgrade. The phone was delivered today (2019-11-19) however it is the incorrect colour. I called Vodacom customer care to enquire about the incorrect delivery, However they referred me immediately to Elite Mobile as they said they were not responsable for the upgrade. When I spoke to Elite mobile they just say the phone was packed by the Vodacom warehouse and it is out of their control. Elite Mobile never told me this was a third party company calling me when they called me for the upgrade, they even confirmed their number as 082 135 being the customer care number. I was under the Impression the upgrade is being handled by Vodacom. The Elite Mobile agent now told me that if i choose to cancel the contract it will take up to 21 working days to come and collect the phone from me. This is absolutely unacceptable. Why did they ship the phone to me if it is not the right item I asked for? I tried to speak to Elite Mobile but they just interested to solve my problem other than telling me it will take very long to have the phone collected from me. They also can not even tell me when a phone with the correct colour will be available.
