Incorrect information provided to me

I spoke to a consultant on the 29.01.2018 from vodacom upgrade and cancellation department regarding my contract,i was offered and upgrade which was delivered to my work on the 30.01.2018 I called vodacom since I thought it will come with a sim card, the consultant told me he is going to request RAM to come and collect the device and he will call me for a new contract with the same offer which was R129.00 10GB day and 10 night for 24 months.. Now the device was collected as the consultant said..but I'm not receiving a call for a new contract with the same offer and now I'm being told different stories like I'm being assisted by people who are not working for a same company.. I want the new contract and number with the deal as promised .now I feel stupid because I'm being transferred from one consultant to the other the data is activated but the device was collected.. And the information I'm being told is way different every day
