Useless support staff

My telkom adsl line has been disconnecting intermittently and when it is up it's less than half the speed i'm paying for. After testing with another router and ISP account I confirmed that the telkom adsl line is responsible for the terrible connection so I phoned and held on the support line ***) for 45 minutes before someone decided to help me. <br> <br> They confirmed that they could see an issue on the line and they would arrange to send a technician, that never happened. I phoned again and suddenly they could not see an issue with the line even though it's still horribly sporadic, I asked them what the line was synching at and it was 1mb, I have a 2mb connection that i'm paying for.<br> <br> Now i'm still awaiting a technician to come and inspect the problem but i suppose that will take another month or so by this rate...
