Telkom really doesn't give a hoot

Telkom are incapable of cancelling a contract and happily keeps debiting my account month after month. I cancelled by ADSL contract on 6 April , but to date it still hasn't been cancelled and I'm still being charged every month for the service that I haven't used since April. I've have been on their agent chat group numerous times, forwarded my proof of cancellation request to three agents, posted on HelloPeter, etc. pleading my case. Every time they say 'it has been escalated' and then nothing happens, and I get charged again. It's utterly ridiculous.

I've got two other cellphone contracts expiring soon so can't wait not to renew these and move over to another service provider that actually provides a service.
