Poor Upgrade Department

I did a pre-order for the new iPhone X on 17/11/2017. Ref number FICWQK. As per the sms "A consultant will contact you to confirm your order from 17 November 2017." 7 Days later no contact from Vodacom. I then went online to do my upgrade. I experienced major difficulties trying to do this so I called the updgrades department to do my updgrade on 24 November 2017. I was told all has been done and confirmed. Saturday 25 November 2017, I received a strange call from an Agent stating she is calling from Vodacom and needs to varify my details. I told her I'm not comfortable handing over all my personal details on phone to a department that I don't even know about within Vodacom. No one had told me I'd be receiving a call. I explained to her very nicely to please ask upgrades to contact me to explain that this is the next step in the process and even apologized if she was a legitimate employee of vodacom, but with the amount of ***** in our country, this call just seemed strange to me especially on a Saturday morning?? She pleasantly told me she would do so. Monday 27/11/2017, I receive a call from cancellations department, wanting to know why I've cancelled my contract??? The consultant from Saturday put a note on the system that "I refused to give my details, so she cancelled my contract!" NOT TRUE AT ALL!! This women from Monday's call sorted everything out and I received my confirmation call. 2 Weeks later and 3 days of constantly holding on at upgrades to follow up with my order and finally today this morning I get through to someone to be told "we are offline" and she will call me back when they are back online, 2 hours later I miss a call from them and receive an sms "Dear Vodacom Customer, we trust you had a great service experience. If your query was not resolved, simply reply NO within 24 hrs and we will call you back." I reply no. I have not received a call back and phoned now to customer care, asked for the complaints department only to be told you don't have a complaints department!! I was put on hold again!! And eventually got through to a consultant at Upgrades to be told, there is no stock of my phone? How is it that 3 other people I know who did there upgrades after me with no pre-order received their phone's yesterday? I am a VIP customer, pre-order done and due to one *********** staff member I now am in the back of the que! I need my query resolved by close of business today and need to know what has actually happened!
