Is giving reference numbers all you can do?

On Sunday it will be THREE WEEKS that i am unable to buy data. The credit is there and available but i cannot buy and nobody can tell me why. I have three different reference numbers oh yes, they love giving reference numbers. I challenged the lady at Vodacom Customer Care to come drop off her phone and SIM card here by e for three weeks - she did not take up the challenge. I cannot fathom how in this day and age i am asked to go THREE WEEKS without being able to buy data.
