Vodacom blocks my account

<p>As from last month vodacom started suspending my account due to</p> <p>fault from their side.i made a call and the call got dropped.so i phoned them.first they told me to reset phone.with no avail.then phoned them again.then they told me i reached my call limit.i checked to see,and i havent used the whole amount that i added if i reach my limits.i had to increas me my limit again,just to use my phone again.i told them that they should make sure that something like that doesnt happen again.this month the same thing happened.i told them to rectify their mistake.but they play the blame game.as they said the problem is on my aide.i told them i want to speak to a manager as i am not going to phone them every month.they shouldrectify their mistakes.i am not getting paid by them so i dont see why i should phone them every month to unblock my line.i feel like cancelling my account and move to another SP.i even phoned cancellations,but their premature cancellation cost are the same as using my account for the remainder.except that i do not get aortime nor data.how can the cost be thay high</p>
