Vodacom are ******

Totally disgusted with Vodacom's level of service. On two counts I have bought airtime and data from the vodacom app, money deducted from my bank but my cellphone number not topped up with my airtime and data purchase. If I call the call center they promise to come back to me but to this moment nothing has happened. I have email confirmation for the two orders but there seems to be no integration as call center agents keep on telling me they can't see anything for my number. First it was airtime for R100 (order number: E***1 ) and then 1G data (order number: E***8). Clearly no one is going to assist me
