Trying to cancel services since June 2017

FOUR attempts to cancel my Telkom services.

Each time I call in, no! your cancellation has not been received and that is using your email address on the cancellation form.

Then the Call Centre tells me that the cancellation has not been captured/processed.

After the first four attempts, still nothing has been captured!

There is no physical place to go to either, why do you Telkom make it impossible to cancel?
