Paid up letter

I paid up my account on the 20May 2022. I was told to wait 20 working days to get the paid up letter. I have been calling your offices to get assistance and your rude consultants keep saying the are putting in a request and I should call again the following week. I feel like I am being ****med and pushed over. When you wanted the money you kept calling none stop. No I need to chase you and deal with rude agents to get the paid up letter.
