Telkom hellkom

I want to cancel my mobile contract with Telkom. I am told I need to cancel online on my profile. My profile does not show my mobile contract and I have linked it numerous times. I want to cancel and no one is willing to help. When taking out a contract with Telkom, it was easy. Now that I want to cancel it's a big issue. I'm going to take Telkom to the cleaners if this issue is not resolved by month end
