Faulty ADSL Line

Hello, i have been having trouble with my internet for months now and nothing is being done.<br> The problems i am experiencing are slow speeds and high latency and it is not my ISP as i have tried multiple ISP's and the issue is still the same. i was told that 96% of my areas exchange is being used and that could mean it is being overloaded or congested. There is a problem at the exchange every week I have to report a problem. i keep having problems so please update the exchange or do something this is very irritating and a lot of people in the selcourt area are complaining about it. Port recreate is also not going to work you have to check if the copper lines or ExchangeDSLAM is faulty and fix the issue im tired of telkoms issues i just want a normal working adsl line without having to phone daily.
