Where is my data?

At 18h55 I uploaded 1gb data bundle from my FNB app. I've been on wireless since 1840. At 19h50 I received a message stating that I'm ok of data. This is impossible. Vodacom or someone is de*****ing my account. When phoning vodacom I get kicked off the moment I get through to an agent. The lack of customer communication is apparent. Also I need data for business tomorrow and don't have time to keep calling a call centre that kicks me off.
