Telkom Landline Account Closure

I have requested for my Telkom landline to be closed on 6 November 2017. According to Telkom, the process takes a maximum of 30 days. The process involves sending an email with a signed document to Telkom (to an account which seems rarely used) and waiting for Telkom to finally close your account. No further communication is received from Telkom. To date, my account is still not closed, but Telkom has not failed to bill me every single month. The current process is firstly unacceptable. Telkom clearly wants to make it impossible for anyone to close their account. I would like for Telkom to immediately close my account and I based on the customer service I have received, I will never do any business with Telkom again.
