Bad service.. the worst service ever

Good day, my account was settled.. a tv that I don’t have for years. I keep calling to ask how do I close this account but no one is willing to assist me. Dudu from the Revenue consulting services then says I need to pay extra .. on the 8/09/2021 I received an email saying I need to pay R 271,50. I paid last week R100 as no this week R171.50 now they saying I need to pay more . I then wanted to speak to the manager who is Gina from the Revenue consulting services who told Dudu to tell me I must email her. Dudu was rude and says I can do what is necessary. I’m asking you guys close my account or I will take this up further.
