Telkom fiber I made the biggest mistake in every considering them in the first place

Telkom fiber. I am still waiting for a working line. Telkom dropped there router and started billing. None of my communications have been responded to. Now they have a company vvm that calls me everyday even though I emailed them that I literally never had a working line. They can pick up the router I never used. But they need to collect that money so they keep calling. My mistake was going to them in the fist place. Now it's going to cost me attorney to sort this nightmare
