Extremely disappointed with @TelkomZA service

I signed a contract with Telkom last year, but from the start there were system-related issues and my eSIM never worked. I have been following up continuously since then, with no resolution or meaningful assistance. None of the service consultants I have dealt with appear to understand what the issue is. In December last year, my number stopped working completely. When I contacted Telkom, I was informed that my account was in arrears. I explained that this was not possible, as I pay my account monthly. I was then provided with the contact details of Elaine from NudeDebt and told that she was handling my account. I emailed Elaine on the same day, but to date I have received no feedback. Each time I contact Telkom, the consultants are unable to assist and seem unaware of my case. This week, all the remaining numbers stopped working as well. I called Telkom yesterday and spoke to Zintle Nkosi, who assured me that the lines would be restored within 24 hours. More than 24 hours have now passed, and we are still unable to make calls or access the internet.
