I do understand that - but it does not answer my question of why @dslmweb.co.za is incredibly slow at 10% of line speed constantly - and how providing you with my details will solve the problem... as its clearly not a problem on my side - and the problem seems to affect quite a bit of your user base..
If MWEB cannot handle the load, whether Telkom is at fault or not, they should not offer the service in 4MB form, rather stick to 512 and 384 until you (or Telkom) can handle 4MB uncapped. I personally would much rather know I can only get 512 speeds, and then pay for that, than pay for 4MB and get 384 speeds.
I could just as easily sell a 100MB internet service, and blame Telkom for not having the supporting infrastrucutre should clients complain.
