Miss information

This Saturday I took out 2 contracts R77 each at game stores cresta. So I had to pay upfront R202 thinking this was the activation and admin fee. To my surprize it was not, nobody informed me I had to pay anything else before the next debit date But today I get 2 notification from my account saying vodacom not paid R157,85.so I called and spoke to a guy informing me theres nothing he can do as now I have rejected orders and this is totally unacceptable. How do you do this to people how do I pay 2 upfrony fees? Is this contract really made to **** me before I even use it? I also dont kniw how you going to get ypur activation fee this month, Coz its going to be like squeezing water out of a rock.whos going to pay for my rejected debit order?
