I've read in two credit repair guides that duplcate tradelines should be disputed with the CRA's. In other words, if a creditor has entered a negative tradeline and then turns the account over to a CA that enters it's own neagtive tradeline, that's a duplication. Has anyone had any success disputing these.
Duplicates are not too hard to delete.. just dispute them as duplicates, list them and the CRA's should delete them. I did that several times now actually..
