Does Telkom still exist?

I have a 10Gig ADSL line. For three months now I used up 10Gig data within half a month. Since 2013 I have never exceeded 4Gigs per month. I have been on the phone with the help lines for hours, I have been to the branch. I have changed codes, login details, unplugged my ADSL line...etc, etc. The last time I complained I have been told that no one can help me and that I should log a complaint via email. The last call-line assistant told me not to expect any feedback on my complaint as they rarely attend to these complaints!! My PC internet tracker shows 1.55 Gig for the month of September however Telkom warns me that I have used up 10Gig, now I cannot do business as I have no internet!!<br> <br>
