Landline and ADSL cancellation not processed by Telkom

I have been trying to cancel my account for the past 5 months and as far as telkom is concerned they just don't give a damn. I've spoken to so many of their call center agents and not a single one could get the job done. I sent through my completed cancelation form with required documents as requested by telkom in February.

So far I have a outstanding amount of R6000 and no use of my cellphone as they linked it to my landline and adsl account that has been suspended.

I'm pretty sure this will effect my credit record. Unacceptable.
