Pathetic Service from Telkom

I am trying to cancel my contract since yesterday, as it is ending at the end of July 2019. I find it absurb that I am not able to phone inn, and cancel. Instead, send a cancellation request from the Telkom App. Apparently in 7 days I will be contacted. So what happens when I am not contacted? I will continually be charged for this contract. All I have is a Case Reference Number, ***3. In my opinion this is pathetic service from Telkom, especially because from the time my contract became legible for an upgrade, your agents have been bombarding me with packages, that absolutely do not suit my lifestyle. Now that I need to cancel, I cannot get through to Telkom, your online chat does not even work. Pathetic Service Telkom. Can someone please contact me, as I want my service CANCELLED.
