Please update my account as paid up.

Having app**** for a clothing account and being approved was a life-changing experience. I have benefited from buying on credit available, very lenient when I have missed my monthly payments. I lost my job and I had started getting challenges in making my monthly payments, got handed over then I settled the debt on the 24th Of May 2021. I received my settlement letter, I immediately called cotton on the collection department then they promised to close the account and report it on Transunion to update my account to improve my credit profile i intended to build to buy my 1st car. even a house. i have been called by MBD for the same account that i just paid up in May 2021. I need help in clearing my name and resolve the matter on my behalf, please. I do thank you for your services and the relationship we have had. but now it's really a frustrating issue that intended to resolve to settle my account and look forward to my financial well-being and managing my account to avoid such trauma of being stuck with something beyond your time.
