No internet for 3 weeks

Telkom is forcing me to pay R700 for a 4mb line (internet), but my internet is down for 2 to 3 weeks. This is unacceptable as I got another neighbour who has the same problem but telkom gave her a 50% discount for the inconvenience .we stay in the same complex but her internet is fixed before mine. I demand we pay a lesser fee next month as Telkom is not fulfilling a service and i am also a pensioner.
