Telkom do not care

I have a 24 month telkom wifi contract and over the almost two years I have called them for half of it. First I upgraded to a 10 meg line that never reach 10 meg mostly 4 meg. And the last 12 months my wifi just keep going off. I struggle to log a fault and its a struggle, calling, smsing, that Facebook is useless. Then I wait for them to fix it. The call centre operators has no answers and are never able to help. Then 3 days sometimes 4 if I am lucky the wifi is back on. This has happened maybe 12 out of the last 30+- days recently. I am currently waiting on them to sort yet another one out. This is day two and I know it wont be on. This morning I asked call center if this is normal and she had no answers. I asked if there is anyone she can connect me with that can help me or explain why this keeps on happening. She says no she doesn't know. I need answers. Don't I deserve answers? I still pay for the lost days but Telkom just don't care. They stick us 24 month contracts and we are stuck with this bad service. How can I just accept this?
