Proof that Vodacom is *****ing from me!

I recently upgraded to a new contract. According to the lady I spoke to from Vodacom's upgrades department, I Receive 10GB once off and the 2GB per month for 24 month free and that I would pay R759 per month for the contract. On Monday 11th December 2017 the handset was delivered to me without a sim card. I phoned Vodacom the following day and the sim card was then delivered but as of today (Thursday 14th December 2017) the sim swop had still not been done and I am still unable to use my new phone. I used my old phone to access the Vodacom app and to my surprise, I was being billed R1532.18 (Image Attached), I was being charged R599.00 for the 10GB that was supposed to be free and I was charged another R367.13 for 10GB which I have not received. Upon further investigation I found that I had only 6.38GB of the 10GB remaining and only 885.08MB of the monthly recurring 2gb. I checked my phone's data usage, and found I had only used 1.56GB on my old phone. I have not yet used any data on my new phone as Vodacom has not yet done a sim swop. How can Vodacom ***** from me like this? I WANT ANSWERS!!!!!!
