Ridiculous Charges

This is nearly the third time that Vodacom has cut me off without warning. We have asked countless times to email, sms , notify if accounts are overdue. After paying our account now they just cut me off? To get my account reactivated is process on its own and takes up time and inconvenience!! Not only do I pay nearly R1000 some months at time for \data"( I have wifi at work and home now) "
