Disappointed with telkom

I have a contract with Telkom and it was handed over to Nudebt, i called the collection company for them to send me proof of when my account was handed over plus the proof of arrangement and the statement showing that I'm paying the account every month and i was told that i need a Court order to get those documents or i can go to Telkom for assistance then i went to Telkom at Alberton City and i was told to call the call center, i called and i asked to speak to the team leader or whoever that is incharge i was they're busy and that was on the 20th of January 2023, i called the call centre again this morning i spoke to Lerato Tlale and he was so rude,he was shouting at me saying he's not going to listen to me but i should listen to him coz he works for telkom. I've been dealing with this since from last week and tired of playing game ,i paid the account in full and i want all those documents today. Your agents don't know customer service, you get send from pilar to post and no one has answer.
