In error; UHEA Lowered my fico score downward by 100 points!!
To no fault of my own. My account was updated incorrectly. Called them to bring this to their attention. Unreachable via telephone. It took 6 months to update my account to good standings. There is STILL damage to the account from their mistake. I would like to give them more stars but they have made BIG mistakes that effect me for 7-10 years of my life. Very unfair
