Telkom wrongfully listed me and handed me over to Attorneys

in 2018 Telkom phones me to say that they changing to fibre and will be giving wireless devices to all users at no cost. Users will stay on the same package. I agree and then the long wait for the device to be delivered. About a month later my phone line is dead and we just cannot get hold of Telkom. Fast forward to October/ November 2018, courier sms's to say the package will be delivered. Package arrives and its a sim card... no phone. Back and forth yet again, a week later the device arrives... Happiness..... NOT. We insert the sim card and excitedly tell my sister (in NZ) to phone us. They phone on our old number but it doesn't ring on our side... Confusion!!!! I phone my cell to see what happens.... again HAPPY because my cell rings. Happiness quickly turns to despair because the number is unknown to us. We switch the device off and next day I make contact with Telkom to say they gave us the incorrect sim card. They insist and say its my number. I tell them that particular phone number we have for a good few years now and we were told back in April that nothing will change. Eventually a agent tells me that Telkom made a mistake. Then.... I get a invoice and a sms to say that I have been handed over to DC FOURIE for non payment...... NON PAYMENT OF WHAT!!!!!!!!!!!!!!!!!!!. I cant even apply for anything now because Telkom has wrongfully listed me. Terence of DC FOURIE has not responded to my emails after me asking him twice now for feedback after telling him my dreaded story with Telkom.
