ADSL Congestion

My 2Mb ADSL line drops to 0.3Mb in the evenings. The congestion gets so bad that I am unable to browse the internet or access my email, due to timeouts. <br> <br> A call was logged with Telkom support. They closed the call stating that I am syncing at the correct speed, and that they provide a best effort service.<br> <br> In this day and age, I find it ridiculous that a telecommunications company does not have the infrastructure in place with enough capacity to provide 2Mb ADSL connectivity, in a major city (Sandton).
