Frustrating Cancellation Process & Billing Without Service

I have been trying to cancel my Telkom account for a long time, but the process has been extremely frustrating. Despite multiple emails and follow-ups, my cancellation request has not been processed. In the meantime, I continue to be billed for a service that has not been delivered. It is very concerning that joining a contract is made so easy, yet cancelling is unnecessarily complicated. This kind of service is unacceptable, and I hope Telkom resolves this matter urgently.
