Mobile contract still not cancelled

My contract with Telkom mobile was supposed to have been cancelled on 13/09/2017. I cancelled this online one month prior as advised. I wanted to keep my number on pay as you go. After many calls and holding on for ages to confirm why it was not cancelled so that I could top up with airtime and data I got silly answers like once cancelled I need to wait 21 days before I would be able to load airtime, I was called to confirm cancellation and I didn't answer which is nonsense, the teamleader just went on tea and she would confirm what the issue was, etc. I spoke to Nkosikona who promised to log a call and get the cancellations dept to call me, Isabella who kept saying she cannot advise why I can only download airtime after 21 days (what do I do in the interim - no data or airtime) and said her teamleader Mariam was on tea and would call me. a week later and still no call from Telkom. Can someone at Telkom PLS ASSIST ME!!
