Telkom is treating me very bad

Telkom has blocked my contract number since 10 April 2025..this despite debitting my account. I went to their branch but could not be assisted, they said their system has been down. I phoned them numerous times a day but couldn't be assisted, I'm told their landlines are done. Did I pay for services not rendered? Is that even fair? I pay for a service so what happens if I don't receive it? Telkom has caused me so much heartache because I have to buy airtime and data, despite paying my lines.
