Quick to list no effort to clear the listing there after

They listed me for not paying Finchoice which was their legal right but I've paid the account in full and I've asked for paid up letter and I was told that it will take 7 to 21 working days.Today I called making a follow up and told that there are no records showing that I owe then nor the records of the paid up letter that I requested.My Name is still listed if the cleaned me on their side why not on credit bureaus.Quick to list no effort after you've paid.It means you get the double punishment
