Bad, horrible service

I requested a cancellation from Telkom on the 30th of October. I was informed, after trying to contact the cancellation agent numerous times, that the request was set for 15 November & that I would be contacted by the cancellation agent and also receive a final invoice. That didn't happen. I received an invoice for R822, which was paid on the 26th of November. But I still don't know if the contract has been cancelled or not as it still appears on my credit report as active.
