Telkom cannot resolve longstanding billing issues.

Since December 2022, Telkom has been unable to produce a correct invoice for the contracted service I have with the company. I have spent many hours with many contact centre agents, none of whom have been able to resolve my problem. Telkom does not provide an alternate channel by which such cases can be resolved, which is an issue for me. It would be great if a competent person in Telkom, who will take ownership of my case, could contact me to help me to resolve my problem once and for all.
