Telkom is a hyena

On the 4th of December I notified Telkom that the contract should be cancelled beginning 1st January.Our contractual term has come to the end.Telkom acknowledged this with an email and sms. Cancellation case number is ***6. service line ***.

Telkom continued to bill me until April this year and my contract not cancelled as per my request. Their call centre refused to close my account stating I have been using the services although their services were suspended several times.This poor service is now affecting my credit record. What they are doing is un ethical and should not be tolerated. How do you continue to bill a client after fulfilling the contract term and notified you officially to cancel. I would like Telkom to close my account and
