Credit Rating, Service, Paid up Letter!

I had a contract with Telkom and I paid it up in November 2019 and requested they update my credit report. I have been going up and down with this service provider to simply update my details or give me a paid up letter to send to the bureau. I then went to Telkom The Grove Mall to ask for one today and to my surprise, I received a rude consultant Matshido, who instead of helping me, directed me to 081180 customer line to speak to a consultant. I then proceeded and advised her that I received my credit report today and it still shows telkom active and showed her proof but she could not be bothered. Is this how you train your people to speak to customers? All I just want is for you guys to provide me with a letter that shows my account is closed as this stupid account reflects badly on my credit rating, it makes me look like I cannot pay my own damn accounts!!! Kindly review this matter ASAP!!
