Disappearing data and airtime

<p>I bought 1gb of data today and used the internet for only a few whatsapp messages and a hotspot for my computer. I browsed roughly 8 sites for a total of a few hours. I did not load any pictures or stream any videos and my data is now at 200mb. How the hell is that possible when in the past I could browse the internet for days and hours and only use a few hundred mbs. I have all background data restricted and every time I try to load their contact page in their website it doesn't work. Not only that but my airtime is miraculously disappearing as well. I bought the 60 mins vc to vc and went over by 3 minute and 15 rand disappeared from my airtime. *** it's not 5 rand per minute for airtime. This happens frequently. I can't find a way to contact them to put in a dispute. And this type of thing is happening a few times a month per client. They are making millions of rand by *****ing from us. What can be done to avoid this? How can I make a dispute and be refunded????? Please help </p>
