Countless unfruitful attempts at Telkom to cancel my service. Yet still being for a unused service

I have been billed by Telkom for services I am not using. I moved to a new address on 30 August 2021 and requested my service to be moved to the new address, which I waited in vain. I then requested a cancellation of service on the 04 October 2021 to *** with the attached cancellation form, but up to now I am still be billed for a service I am not using. My service details are as follows: *** SmartVoice 100; SoftCap (600GB) and TIN*** Third Party Access Capped Internet.
