poor service

I am very disappointed with vodacom service.i tend to wonder what security measures are put in place to protect their clients when it comes to *****.In May this year ***** took place on my acount which was causes by vodacom staff member who never verified if that was a legit customer.all of a sudden my modem wasn't working and the debit order has stopped.then now in October a debit order for 4 months went through on my account even though the modem wasn't working.i demand my money back to my account because I didnt cancel the debit order and now to activate the simcard im requested to pay more money.i request my simcard to be activated without me paying the activation fee due to the fact that I never stopped the service.
