Horrific

I paid an account I full on the 17th of July 2025. I did not get a paid up letter upon payment and have been running up and down try to get it so I can update my credit report. I have lost track on the number of times I have been told "it will take up to 72 hours". I have sent numerous emails, whatsapp messages and made a number of no phone calls but I do not receive any response or I am told stories. My next step is either the CFDC.
