Telkom service worse now than ever before

Struggling to cancel a contract with Telkom since February 2018. Communication with 8 or so consultants, call centres and numerous emails have had no results. Telkom took more than a year to collect a package and have charged me R2800 for a service I did not receive. I am tired of computer generated emails. I have confirmation that the case is closed but I found out that I have been placed on debt review?? Looking for advise to challenge this legally. All records and documents are available as evidence of communication . Is there one individual who will actually take a call and focus on customer satisfaction.
