POOR SERVICE IS THEIR POLICY

I bought 3GB data on Friday, 24 July 2020 and used it for about 45 minutes. Today I tried to use the router and found out that the data has been depleted. I then bought 5GB data. Used it for about 45 minutes again, and it is depleted. When I called Vodacom and explained what happened their response was that my data is depleted so I can't connect to internet. I needed explanation and the call center agent was so rude and asked me what do I want him to do? This is beyond poor service...
