My data started running out fast few days ago

I don't top up data normally, this month I run out off data and had to purchase 2 Gigs on the 19th and on the 26th.<br> I monitored my data and saw that is running out very fast, i cleaned my Mac and browser and connected without anything opened, still data was running out fast. Tried calling 180 several times without luck. Then today I opened a chart with Busisiwe and she was not help full asked her for a call back as my data was running out and she went on asking questions, final got a call from her and she transferred me to Nomalanga in data section. I told her what is happening and all the steps I took to find out what the issue is but she told me something is running on my system I told her I used two systems and even re-installed one and the issue is still persisting, she told me she can't do anything from her side. I then asked her what should I do and she placed me on hold for more that 15 Min and she hangup on me. I need my issue looked at and resolved as I need this connection to work and I can't keep on buying data that I'm not using. The last netstat I run showed 12 connections and local address was 8ta-147-63-14.te with different ports. I also will like my money back.
