Service non existant

I have been trying for about 4 months to cancel my landline with Telkom but to no avail, I am not even using the line, it's active on a different property and I am still receiving accounts for the line. I sent an email request for cancellation of the line on 15/05/2017 and contacted the call centre twice on 29/05/2017 and 30/05/2017 and after a long wait someone eventually answered, I had to explain and spell information over and over again after which I was advised that the number will only be blocked, not cancelled? I requested that the line be cancelled end of June when I moved into a new property. Still no cancellation. There after I visited Telkom twice and completed forms but to date still no cancellation. I tried to contact them again today on 10210, 10213 and 081180 and after entering my telephone number held on for almost 10 minutes without any response, just ad jingles playing over and over. This is not acceptable at all. In the meantime I am paying for a line that I am not using as I don't stay in the property any more.
