TransUnion Credit Reporting Complaint

TransUnion Credit reporting department,

Incorrect information on credit report Information is not mine Massachusetts

I have a $500.00 collection on my Transunion credit report which I tried to dispute online but they would not allow the dispute. I do n't know if it was a technical error or they just have it set up so you ca n't dispute which means less work for them. I have tried to get a free copy of my report but they say I cant because I read it online and now they want - per month to do what they are required to by law for no charge. Total ripoff and I 'm -. This is not my account and it is destroying my credit and it is only on Transunion
