VODACOM gets my migration completely wrong!!!!

So after receiving great assistance from Vodacom employee with regards to the downward migration of my contract, the nightmare on the 30th September began. Firstly I was not informed that I would have downtime from the 30th September due to my migration. Secondly I loaded data a day prior to the 30th, 4gb of data, an that had fallen away due to the fact that the consultant never advised me of this. So therefore I would like it to be loaded back to my account Vodacom. Thirdly, the 1st October arrived and guess what, instead of allocating my 500minutes and 1 GB of data, Vodacom only loads 300minutes and between 400 and 500 MB of data!!! To date nothing has been rectified. Lastly, when accessing or trying to purchase Just 4u it says I cannot purchase due to the fact that I have an unlimited contract which is no longer the case. VODACOM I would like my minutes and data back please as well as the remainder of the 4gb of data I had on the 29th September...
