My TransUnion ( TU ) credit report has the incorrect information as to my " Account Age '' which factors into my credit rating and is why my TU credit score is significantly less than XXXX. TU is reporting the Length of Credit History as only being 13 years and 0 months, Average Account Age of 5 years and 11 months and the Oldest Account being with the XXXX XX/XX/XXXX. The correct information which is being reported by the other XXXX above mentioned credit agencies should be as follows : Length of credit history - 21 years, 10 monthsAverage Account Age - 7 years and 11 monthsOldest Account - XXXX XXXX open XX/XX/XXXXEssentially TU deleted my oldest account ( XXXX ) which has now changed all of the calculations for my " account age ''.
