Caller tune subscription nightmare

I have been trying to contact Telkom customer care, I called 100 and 180 however when I select an option from the voice prompts in regards to the contact number I am using as well as the language I would like to be assisted with, the automated machine sends an sms that has a whatsapp link, I tried using the link to resolve my issue however I cannot seem to get assisted, all i need is to cancel a caller tune subscription which i do not remember activating, once I load airtime my minutes disappear Can someone attend to this ASAP
