No response for 5 months

Background: I cancelled my contract with Telkom in Sep 2015, the actual cancelation on Telkom side was only processed in Dec 2015. <br> This morning I received a notification that I have been handed over to Debt collection for the outstanding 3 month (Oct to Dec 2015).<br> I have made numerous phone calls to try and resolve this and have even logged a previous complaint on HelloPeter. <br> Telkom has not once phoned me back as promised, their service is an absolute disgrace and I will never use Telkom service again or recommend them to anyone.<br> If this matter is not resolved, I am taking legal action against Telkom for Defamation.
