Continous bad service and services

My ADSL service has been beyond terrible for the past 2 months, I have reported it about 5 times and nothing they are continuously closing the faults as completed with no confirmation that the issue has been resolved. Do I get a refund for the past 3 months or terrible service? <br> <br> 1275CRK250315 Noisy Open Wed Mar 25 21:12:23 SAST 2015<br> 913CRK230315 Slow Access Closed Mon Mar 23 12:00:38 SAST 2015<br> 1984CRK020315 Slow Access Closed Mon Mar 02 20:37:15 SAST 2015
