Telkom Absolutely Useless!!!

I upgraded my landline account to an ADSL account in June 2018. The OpenServe technicians have, to date, still not upgraded the line or installed the WiFi router at my house. Even though they never upgraded my line, Telkom have been charging me for the service since June 2018. I have complained about this in-store and with their customer service call-centre and informed them that I refuse to pay the account until they complete the upgrade. They subsequently cut my landline and continued to bill me for it. I again went in-store to try resolve the issue. They insisted that I pay the account before any investigations would be conducted. I refused.

I tried the call-centre again and their response was that the account had been suspended and they cannot do anything until the account has been paid and the account re-activated. This problem was escalated to their management in September 2018 and I have still not received any feedback from them. The Account was then handed over to their attorneys for collection.

In February 2019 I received an email from their attorneys stating that I owed their client money and that I could be taken to court. I informed them that I would gladly go to court to state my case and still refuse to pay the account. The attorneys never made contact with me again. Sometime after that I received an anonymous SMS that Telkom was going to report me to the Credit Bureau, which they did.

In October 2019 I received a payment demand via email from National Debt Connection where they also threatened to drag me to court. I refused to pay and also told them that I would gladly go to court. Haven't heard anything further from them either.

I am now blacklisted for failing to pay for a service that I have never received and it appears as if this issue will never be resolved. Can anybody help me?
