noisy line and ASDL line not working properly

This is not the first time that we have had to log a fault with Telkom, and every time it is a noisy scratchy line and the ASDL line does not work properly either. We have been told before by Telkom worker that down the street from us, there are neighbours connecting to our line *******ly, the Telkom person spoke to them, due to the fact that the line was also noisy, but since then we have had endless problems with our line. We report it to Telkom they send someone out and we have connected a pots filter done all that has been requested, but it still remains a problem. It is getting to a point where hunting for alternative to Telkom as this is just no on paying for a service we are not getting, we reported the fault on the 29th Dec 15. We have not heard anything from Telkom and still just wait on them
