Vodacom Airtime advance unfair practice

I am totally disappointed in the way Vodacom handles business. I am not impressed with the Air Time Advance. First you could buy for R10 and if it is paid, you get to buy another R10 advance. The USSD script is designed in a misleading way, clients buy by entering a "rebuy" unintentionally. This has happened many times. Instead of "cancel" you input rebuy. Remember this is a loan and how do you know if this person can afford this loan. This is totally an ********* way of doing business. Customer Service is terrible and trying to get to the right place is even worse. Third parties are pushing their services and not even thinking of the poor.
