Lack of service

Telkom has left me without ADSL service for over 10 days. Banks and other companies assume that correspondence is received almost immediately. Also, payments etc. Have to be made. I have complained every day, and all they want to do is supply a new reference number with a more recent date. They have the monopoly on ADSL lines, so I cannot go to another supplier. Alternatives are generally slower and more expensive, so something needs tp be done. It is not acceptable to leave one without this service, even more than 2 days. A few years ago Telkom did some day service, now service is non existant.
