Request Cancellation of Telkom Service

I’ve been trying to cancel my Telkom business line for almost 2 months now. I have spoken to the call center agents about the cancellation, they advised me to submit a cancellation form, a letter written with a company letterhead as well as my personal Identity document. I submitted this to their cancellations department which can only be reached via email on ********** The cancellations department responded with an automated email acknowledging receipt of my request to cancel the service. It’s been well over a month at this point and my service is still not cancelled. I have spoken to a number of Telkom call center agents asking them for a follow up and they all say that the service is still active and nothing has been done to effect the cancellation. The call center agents say that the only way to get hold of the cancellations department is via email and they are not contactable in any other way. This is ******* what Telkom is doing, you cannot keep a customer from leaving by doing these things
