Telkom - A bunch of unprofessionals, *****s and idiots

My landline phone was cut (because it was a copper line) without informing me in May. When i subsequently phoned to ask why my phone is not working while Telkom is debiting my account diligently every month, I was told it's because they are moving to a new technology. I was told that they will send me a new phone. I have more than R 6,000 worth of credit in that phone. After phoning, emailing and going to their physical store, the issue was not resolved. I even asked for my contract to be cancelled and get my money back, their billing department said they can't refund me. They transferred me to their sales department who has again promised to send me a new phone that I still have not received. Whenever, I phone Telkom, I spend no less 45 minutes because I get transferred from switchboard to progress department, then the progress department transfers me to technical department, technical department transfers me to billing department, billing department transfers me to new sales department. I have wasted my time and money (debit orders and calls cost) to try to resolve this issue. I even had a "Trevor Noah's moment" once with their agent who said that they have been trying to contact me without success. I asked what number did they call. And they said they called me to the very number that was disconnected. How stupid can they be? The most frustrating thing is that I can't cancel without losing my money, and I don't have any legal recourse to get justice.
