On ITC because of account cancelled long ago!!!

I cancelled all services with Telkom on the 3rd of November 2015. I have proof of cancellation sent and also proof of receipt of cancellation from Telkom. Telkom however kept billing me, and also proceeded to slander my credit record to a point that I am now not able to apply for a bond because of this.<br> I called the Telkom Call Centre on the 14th of March 2016 and spoke to a lady Nosi [Email Removed] She logged the complaint and gave me reference number: ***1.<br> On the 17th of March when I received no feedback from Telkom I called the call centre again and spoke to a Supervisor Siviwe [Email Removed] whom requested I send all the proof of cancellations again. I sent all the correspondence again, and he advised me that I pay the full outstanding amount of R2200 before Telkom will investigate. <br> My life is currently on hold and my credit record ruined because of Telkoms incompetence.<br> I insist Telkom sends me a letter stating that I do not owe them anything, an apology and clear my name at the credit bureau. I have also lost income due to these proceedings
