Non Cancellation by Telkom

I have been fighting with Telkom since January 2018 about a cancellation of a data contract. I've been debited an amount of R1700 odd for services I have not utilised, also I did not give permission to renew the contract and the lawyers that they used to collect have now stopped contacting me as the 3 year period has expired in terms of the Consumer Protection Authority. I have been in contact with Telkom, ICASA and the Consumer Protection Authority regarding this matter. My cellphone contract is due for renewal on 24th June and due to the outstanding amount I am not able to renew. I have 2 SIM cards through Telkom and will be cancelling them both. My family of 7 are all on Telkom so guess who will be losing 9 contracts.
