Transunion sent me a Fraud Alert / Security freeze application asking if I would like to place a security freeze on my credit file. My response is no. I do not want a security freeze on my credit file. I did not complete nor submit a credit freeze application. Transunion then placed a security freeze on my credit report without my consent and now my potential creditors are unable to access my Transunion credit file. This blocks my ability to purchase a house, to purchase a car, and my ability to obtain general credit. Transunion then further lowered my credit score to XXXX although I have only XXXX active credit account and no lawful negative accounts. The XXXX account being reported is PAYED AS AGREED and has never been late. My credit score should be a XXXX. Please assist at unfreezing my Transunion credit file and lifting my credit score! I did not request a credit report security freeze. Unlock immediately!
