Cannot cancel my contract

I want to cancel my contract, so I call 081180, then the voice prompts tell me it will send me a whatsapp link to help with my queries, then the whatsapp link says I must call 10213, then when I want to follow up with my cancellation the adviser told me I must call 081180. I want to just cancel my contract, Telkom is the most useless service provider. I go into the store to cancel my contract, then I am told to call the 081180. I will never ever use Telkom again.
