Pathetic Service

I logged a call on Saturday (4/11_2017). Ref number is 186CRK041117. I have been having issues with my ADSL Line for the past 6 months. It keeps disconnecting every few minutes and im unable to get the speed i am paying for. Technicians have been to my premises on numerous occasions and advised that the underground cables seem to be the problem and need to be replaced but nothing has been done about it. I have still not received any feedback on the latest call logged.
