You must be out of your mind to do business with Telkom
You must be out of your mind to do business with Telkom. 
After instructing an attorney to give notice of  termination of a deceased person's landline and ADSL contract with Telkom, Telkom promptly terminated the service a month later, as requested. The account was fullly paid up until the end of the month during which the service was terminated.
No further accounts were submitted to the attorney and no claim submitted to the executor.
Six months later Telkom handed the account over for collection, the debt collectors referred the matter back to Telkom. Then Telkom advised that the service had been cancelled due to non-payment. The attorney contaced Telkom again. Telkom was requested to submit a claim against the estate or to issue summons, which would be defended.
The account is still debited every month, despite Telkom saying that the service had been cancelled, and the account is still sent to the deceased's unserviced mailbox, despite numerous requests to send all correspondence to the attorney. 
Nobody at Telkom listens and nobody feels like sorting out a problem.
It also seems as though Telkom is the only company offering fibre service which doesn't use underground cables, making it a higher risk for service interruptions.
I was considering subscribing to a package with Telkom, but fortunately I didn't.
