Floored System *135#

Vodacom has this service *135# , to buy airtime , did you know on a top up plan should you have more that one contract on your name for your spouse or kids , they can purchase data , airtime , anything and add it to your billing without you being aware of this and there is no way of controlling this, this is a Vodacom system set up for Vodacom to make money and to put the customer at a disadvantage whilst they make money , paying a contract of R818 , and then receiving more bills on that , how many other people is vodacom abusing in the same manner because of the system. I made it clear with the consultant , what i sign for , i dont want any additional charges , yet their are recharges I am being charged not authorized by account holder , yet they wont allow the other person to call for help with something with their line only account holder can call for help, but you telling me . none authorised people can impact my billing , well done Vodacom
