Telkom keeps charging even when line is cancelled

TRYING TO CANCEL MY TELKOM ACCOUNT. CANCELLATION OF LINE **********

I have been trying to cancel my account since October 2017. Cancellation has been done several times at a Telkom branch and complaints has been escalated. All was done exactly according to cancellation policy and the initial cancellation was well in advance. Each time I get told that the problem will be dealt with immediately and even received SMS confirmation that it has but Telkom keeps charging. When I try to get in touch with the person who is dealing with the problem they suddenly disappear never to be heard of again. The last person I talked to was Sieongile (spelling might be wrong) with email ********** I have refused to pay and now they apparently handed me over to the court for non payment. Our house where the line was, was sold and the new owners installed a new line in the first week of November and the old one (mine) was disconnected. Apart from not living in the same province anymore, the line is physically disconnected and cannot be used but still I get charged. . TELKOM SORT THIS **** OUT AT ONCE.
