Airtime/ data always depleted

<p>It is very difficult not to get angry at the call centre staff, especially when they are just doing their job. However, it is absolutely ridiculous that one would load airtime (including data) and then it just disappears. </p> <p> </p> <p>This happens way to often and I am starting to get fed up with this. MTN's service delivery and airtime or data management is absolutely pathetic. I will most definitely cancel all contracts and always inform people to stay clear because of this.</p> <p> </p> <p> </p>
