I didn’t write the credit bureaus, but on each website, there is a place where you can dispute anything and everything on your credit.
You tell them why you dispute it, if you have receipts, correspondence, or whatever. They investigate it, and if they would like to see your receipts and such, they will ask you to send it. But in my case, they just removed it.
Dispute everything! I was told to do that by a credit counselor. I did, and the businesses that don’t respond within 30 days, are removed from your credit report whether or not it was valid. Hope that helps.
