Telkom inefficient lack of service

I have been trying since September to sort my account with Telkom out. Starting with transferring the service from.my deceased Father's name into mine. I have not received a bill since, I cannot get onto the self service portal. I have made numerous calls, sent numerous messages on their website, payments are not being allocated, calls are not been logged onto their system, there is no willingness to help me with my issues, one can't escalate.higher than their call centre, I can't even cancel my service as that does not work on their website. I want to know where my money is and why I have to pay for a service that I don't have.
