Telkom misery

I am now reminded why I feel so much joy cancelling my last Telkom phone line (previously I had 4 plus internet) so that I never have to deal with this company again. I have followed all their rules on the cancellation process but despite waiting 30-days and at least 10 emails the phone line has not yet been cancelled and statements are still arriving. Have not been contacted by Telkom at all. Big time frustration.
