inexperienced support staff

please can you guys hire experienced and trained staff on your chat support facility. I feel as if they dont know their job. I have always had my ADSL syncing at over 9mbps in the past 10 years. Recently I opted for an 8mbps adsl account for it because of costing. the line used to sync perfectly at 8mbps, but over the last few months its degrading and I'm now down to 6.4mbps, There is a lot of noise on the line which has never been fixed, instead telkom prefers to degrade my speed to compensate for this. Please can you resolve this issue with the line so I can get back up to the 8mbps+ speeds I enjoyed before
