Data dissapearing

I am at my witts end. After the previous complaint Vodacom imbursed me with 2 gigs...but can not tell me where the data is going...because the system not working. This morning the data finished.. I loaded it with another gig. 1 hour later ...pew. Gone. Iand my work is standing still. I am really in tbe worst space what this service provider is concerned and i am considering to go to cunsumers court about this. I phoned again...but they cant help me because tbe system is off
