Paid up letter

I paid off my account on 4 November 2021 and sent them the paid up letter. I called them today on 6 December 2021 to enquire as to whether my account has been updated from their side to reflect this and to ask whether they have sent a notice to Transunion to clear my name. I was told my account has still not been updated and essentially nothing has been done to clear my name! I am livid that nothing has been done from their side. I will never again get any store cards or anything from RCS!
