Cancellation of service

We want to cancel our ADSL line with Telkom.I completed the cancellation form and sent it on 25 July 2017 to the email address indicated on the form.On 5 September the service has still not been cancelled.I spoke to Gongwana and she will follow up.Never heard anything from her.On the morning of 2 October I called the client service centre AGAIN as the service is not cancelled yet!Nolundi can not help and Ziyanda,the quality assessor, will call me.At 14:53 I called again and spoke to Boniswa.She also will ask Ziyanda to call me back before the end Monday.Until now,3 October,I still have not received a call from anyone!In the meantime I have to pay the account (which was supposed to be cancelled on 1 August already!) otherwise they cut my service! WHAT PATHETIC SERVICE IS THIS!!!!
