CLARITY PLEASE!

Woke up this morning to find my airtime and data bundle on R0.00, 0MB. I find this impossible. I called Vodacom and the consultant was only able to tell me what my last calls were and what they cost. ALL I want to know is how much money I had to begin with on, for example, Monday and then to physically see how my airitme got eaten up. I find it impossible to have used R200 in a few days. I barely call! I then went in-store where I was assisted HOWEVER she was not able to do anything because the system was super SLOW! (How ironic), however she advised me to register online and get the statement online. I did so now. I could see my last 10 transactions which is all data usage till approx. 5:55am which in conclusion tells me my airtime finished before my data WHICH NEVER HAPPENS because I HARDLY DO CALLS! I then requested a 30 day report of which I paid R10 for. ONLY to find that the statement only states what the invoice amount is and the debit order received. So I STILL DONT KNOW WHERE THE HELL MY AIRTIME RAN TOO!!!!! HOW CAN I GET ANSWERS! I've tried the call center, in-store and website! All have costed me additional UNNECESSARY costs! Time to change service provider!
