Worst Service Provider ever. No cancellation since April, Still paying in July 2018

Worst service provider ever. Filled in my cancellation form April 2018. As yet 03 July 2018 - no response. Tried calling numerous times, tried messaging thru facebook numerous times.. Nothing. Thats how important the client is to Telkom. These people dont mind taking your money for nothing, but when it comes to sorting out cancellations and complaints no response. So Upset, been holding for a full 10 minutes, adds and more adds..
