Billing

For the past six to seven monthly billing accounts I have been charged ridiculous amounts like between R5K and R12K per month and when I enquire I am given a technological answers which do not make sense to me that it is data usage. I personally do not use a lot of data on the phone because I use the company data when I need to go on internet, it is not like maybe I'm running a business. The charges are just crazy!!! <br> Right now my line was suspended, I could not make calls and when I call the call centre they cannot tell now why is my line suspended.<br> Can someone at MTN look into this because it's continuing and do reversals.<br> <br> Frustated!
