New billing launched and nobody knows what it is

I got an sms from Vodacom that I had been moved to their new Customer3D billing, and I would receive 1G of data on 23 July. I could opt out before 22 July. I didn't get the data, so I called customer care on 23 July,and spoke to Matifa. My first question was \What is Customer3D billing?". She never heard of it"
