MTN *****ing data from customers

My daughter has a data, airtime and sms package on contract. From May to September, she would suddenly have her data and airtime taken away. Then she would get an sms saying that she should purchase more data now. This happened for 5 months and my husband contacted their customer care number a number of times to request a URL report. Each time he was told, they would send it. However they never did. After speaking to a senior person at the call centre, they sent the October URL report and NOT the ones requested. October no data disappeared and this is the month they choose to send a report on! How convenient! In November, the data and airtime disappeared again which means she lost 200MB of data and R100 of airtime again! She has wifi at home and at school and her phone is set to only update when she authorises it. Her phone is switched off at night. She posted it on FaceBook and asked people to respond if they had similar experiences and lots of people have had the same experience. Is this MTN's way of making extra money?
