Frustrated customer

The service from Telkom has been appalling! I have been trying to get a fault on my landline resolved from June last year with no success. The contact center is extremely unhelpful and I refuse to pay for services we are not receiving. Last year we reported a fault on our copper line that we were forced to then migrate to a Fibre line. The modem was installed however the team never returned to complete the installation. We have been contacting 10210 for assistance but the response is always they cannot help as there is an open service ticket. When we contact the services number on 10213, we are told numerous reasons....that the ticket needs to be closed by an external person or they cannot find an open case. The first thing the consultants request is the outstanding to be cleared to help. We have tried clearing the balance to get assistance but this continously gets dragged to the next month and our account is credited again and we are back to square one! This is beyond ridiculous and we now refuse to continue paying for non service and the lack of support from you to help us get this resolved. We have been loyal Telkom customers for over 30 years but your service has truly become the worst customer experience we have ever encountered. I would really like to have my services fully cancelled...however when that seems to be posing a significant challenge!!!!! I would really appreciate any support in helping to close off this issue or help in cancelling my services as we really don't want anything to do with Telkom after this experience
