Dishonest service from Vodacom

It's 27 March 2019 and still Vodacom cannot assist me with my upgrade problem. I upgraded with Vodacom upgrades department in February 2019. I upgraded 2 of my cellphone lines and Vodacom offered me 2 new free Huawei Tabs with 12 months data for 250mb every month. Vodacom sent me the handsets and the Tabs but didn't send me the SIM cards for the tabs. My upgrade date started 1 March 2019 and I cannot use my tabs. After my first review on 4 March 2019 with Hello Peter I received 1 response on Hello Peter and upto now my data is not available for my tabs. Vodacom customer care told me that I must Rica 2xPrepaid SIM cards and Vodacom will load the data for 1 year on the SIM cards,today (27 March 2019) I phoned Sasha at Vodacom after sales department and she told me that on the system it shows that Vodacom must courier 2xPrepaid SIM cards with data on to me, but up to now I didn't receive it. I have purchased 2 x prepaid SIM cards and I have Rica'd them on my name, can't Vodacom just load the 12 months data on the SIM cards which I have purchased and Rica'd - as I was told to do by Vodacom customer care and I have the email from Vodacom as proof.
