Data gone without using it

On Tuesday I bought 1GB and when I tried to use it I couldn't, I then tried to call the Vodacom Customer Care line and it was not getting through, as I was worried about that and when I checked my phone it no longer had network. And this happened from 14h00 till midnight and my 1GB depleted without me using it because of Vodacom's network. I then logged a fault using my other number from another network and they responded by telling me that they were fully aware of the network problem that was affecting many of their clients and it ended there. So I want Vodacom to reimburse me with my Data or the amount I used to buy that Data
