Requested for a Paidup letter from Telkom and did not receive it

After being in arrears with Telkom I paid up my account on 23 April 2019 . On this date is when my payment reflected on telkom’s side. I requested a paid up letter and they sent me a message to wait 10-7 working days. I called back after 10 workings days and received the most horrific service of my life. I was treated with disrespect and arrogance. I phoned 5 times and 5 times they have escalated my request to back office with no response. I am beyond fustrated with Telkom. I just need a dam document that states I paid up my account and I never want to hear the name Telkom again.
