I purchased a XXXX years ago. I paid on time. Towards the end there was an amount due and XXXX gave me permission to make the last amount in payments. They messed up and marked me as late to the credit bureaus. In 2009 I received a letter stating they had contacted the credit bureaus and marked me as not being late ( see attached ). Every credit bureau except TransUnion changed their records. In the meantime I have dealt with the deaths of XXXX parents as well as XXXX. I am coming into some money and low and behold TransUnion still has not changed my score. This will affect my ability to buy a house. Please see the attached letter with a barcode from XXXX which proves beyond a reasonable doubt they did the right thing. Also please note all other credit agencies do not show a late. Only TransUnion. I want this removed from my credit score with TransUnion. This letter from XXXX is from 2009. 
Thank you, XXXX XXXX
