I regret signing up with telkom

Following up on my previous review, I had a problem with telkom's current months statement. I was informed the situation would be sorted out in 72 hours and someone would get back to me. I was charged penalty fees for an alleged outstanding fee which I didn't have knowledge of since im debited every month. Suddenly I receive a message threatening legal action against me. Is this how telkom resolves problems customers experiences?what happened to the resolution they promised me since they told me its a backlog from telkom??
