Clear my name on credit checks and give me my paid-up letter please

I made a review on the 6th of July 2023 about Avon not wanting to give me my paid-up letter since i paid their account full amount through Shapiro Shaik Lawyers on the 6th of June 2023 and i was told that i am still owing, now i have been sending follow ups emails to Dimakatso Jane Sishange and she's been ignoring and avoiding my emails. Is this how Avon operates, what was your purpose and reason to take me to lawyers while knowing that you will say i am still owing while i paid full amount of the money you said i am owing
