Unstable Connection

Since May of this year, my internet connection has been constantly dropping me with Lost-Carrier errors. I have reported this to Axxess and they have done multiple port resets and line tests which have not resolved the problem. They suggested that the fault could lie with my equipment, so I bought additional POTS filters, phone cables and pulled out an old router. Over the next few months I have tested with a combination of these but still to no avail. Even with the different cables and routers, the problem still persists. I have since logged multiple calls regarding this issue but it is still not resolved. They opened a call with Telkom, but in usual Telkom fashion they sent an sms saying they are busy and then decided to close the call just because. I have since logged more calls with Axxess and after doing yet again a line test and port reset, they suggested it might be my equipment and only after testing the equipment, can they call Telkom. I pay them quite frankly for the line and the connection, I should not have to jump through these hoops to have my problem solved. And that is all I want, the problem solved.
