No response despite numerous reference numbers given

Relocated in Oct 2017 and tried to have my landline moved as well. Telkom took all my details and I never heard another word from them. Followed up in November 2017 and I was told there is no Telkom service at my new premises and the line would have to be cancelled. I sent a cancellation form through as per their request and not another word since. But they do remember to debit my account every month for a service I don't have...non-existent service and would not recommend them to anyone.
