Very irate about service

So overall I have no complaints with Vodacom, but today takes the cake. I upgraded my contract last week and yesterday my debit order goes off -So I assume all went well and I'm impressed with the service etc.... This morning when I woke up NO DATA and NO WIFI! When I called Vodacom I spoke to a very helpful Thuli who tells me that Vodacom never correctly upgraded my contract and that they have not allocated any DATA to the WIFI.... and the cherry on top of the cake is when she tells me that they need 3 - 7 work days to correct their own ****!!!! Great!!! So now I need to buy data (on top of my monthly premium that I pay ) as Vodacom neglected on their side.... and I REFUSE to accept this.... I want this fixed with a proper explanation A.S.A.P!!!
