Telkom service poor

So Monday Morning we wake up with no internet, I then called Telkom to find out what is the issue we tried to resolve it but no success the lady I spoke to were very friendly and helpful, she took down my number and said they will let me know what the outcome is, I here nothing, I call again with them saying it was cable that was ****** okay no big problem they will resolve it they will let me know I wait and when I heard nothing again I called the next morning again to find out that the cables won't be replaced I need to look for another service provider, I must cancel Telkom, i must pay this month which is understandable but then i have to pay end of March again, Why? Why pay for Wifi I'm not using?
