Continuous faulty ADSL line

Hi,<br> <br> I have been experiencing excessive/intermittent ADSL service (DSL line sync) on my landline since October 2015. My ISP Afrihost has diagnosed the issue, and advised it is Telkom related. I have gone performed extensive testing/troubleshooting such as, changing the ADSL modem, checking the POTS filters, changing ADSL account, disconnecting all telephony appliances. I have logged numerous calls with Telkom. Each time they perform some action and the line is stable for 1-7 days then the issue re-occurs. Twice the engineer was at my home but they detected no issue. At times I have heavy latency and/or my ADSL speed fluctuates from 4-8MB. As my ADSL router sends me an email each time a new connection is made, as such I have proof of this issue and it's approximate start date. I have even gone as far to order a new Telkom line because I can not get the Telkom to perminently fix this issue.<br> <br> Reference Number<br> 360CWK301215<br> 158CWK301215<br> 269CWK241215<br> 10CWK191215<br> 4CWK111215<br> 630CWK201115<br> 524CWK131115<br> 448CWK161015<br> <br> Please help?<br> Thank You
