ADSL speed only 3 MB / but I am paying for 10 MBs

I am paying for 10 MBs ADSL, but I only have 0,3 MBs to 3 MBs (maximum)<br> The Telkom ADSL line is ***<br> I have reported this numerous times. <br> Telkom technicians have come to my house on several occasions, but they all are unable to resolve the problem. <br> My internet service provider says that the line can only sync at 6 MBs, and that this figure is erratic. <br> My most recent Telkom escalation reference is: 693232<br> Can Telkom please advise why my line will not sync at the 10 MBs that I am paying for?<br>
