Frequent Calls from Telkom Call Centre Despite being asked to not be contacted and removed form Database

I keep receiving phonecalls from the Telkom call centre ***):

Thus far, I have received calls from this number on the following dates:

2020/04/17 2020/05/06 2020/06/11 2020/07/01 2020/08/06 2020/08/07

Despite telling the consultant that I am not interested in their offers. I have also asked to be "Removed from the database" and to "Stop being contacted" but I assume that I am not able to be removed as I am an existing Telkom customer with both a mobile and internet package where the contract has passed it's miminum date.

I continue to use to Telkom's services but if I frequently get contacted with offers to sign a new contract whether internet or mobile, I will take my business to another service. If I was interested in purchasing other services from Telkom, then I will contact the business myself as frequently offering me products is alienating me from the business more.

If I continue to receive calls for upgrades or promotions from this number then I will have no choice but to contact the National Consumer Commission with a complaint.
