No service

I've had my Telkom adsl line for about 2 years now and since its been installed I've been having faults that the Internet just dies and won't work. Every 2 to 3 months I hav to call in to have it reset (because they refuse to send a technician out I've only had one once) yet again my line is down and I hav to wait a week again. This time again I've been told I need to wait till mid week next week which means another weekend without Internet. The supervisor siya refused to put me through to a manager and flat out says there is nothing I can do but wait till they get to my problem. Yet when I need to pay my account it needs to be done on their time! Shocking unacceptable service yet again
