If you dispute too many at one time they throw an identity theft warning on it. That could be it.
I personally got tired of all of the erroneous information on my credit report and fired off massive certified letters with a return receipt and have had 3 identity theft warnings put on my credit files.
You did nothing wrong, it is the erroneous reporting and oversight by the credit reporting agencies that are to blame.
My advice is this:
1. NEVER NEVER NEVER NEVER NEVER talk to a collection agency on the phone. In writing everytime. Tell them all communication MUST BE IN WRITING. Everything you send them send certified mail with a return receipt. PAPER TRAIL PAPER TRAIL PAPER TRAIL.
2. NEVER NEVER NEVER NEVER NEVER NEVER dispute anything on line. You will just get a canned response. Always dispute with a handwritten note that forces someone to physically look at the letter and it wont be scanned into the computer and give you a canned response.
STUDY THE FDCPA AND THE FDRA and learn it backwards and forwards.
Collection agencies and Credit Reporting Agencies know that the average consumer doesnt know jack about their responsibilites and requirements to safeguard consumer data and they fall short across the board with these responsibilities.
I have even written letters in crayon because (purple) it cannot be scanned into the computer and thrown up to some 8 dollar an hour employee that doesnt give a jack that erroneous credit errors effect my borrowing capacity and the quality of life for my family.
Learn the rules and WHAT THEY MUST DO and stick it to them.
Your credit standing is your LIVELIHOOD and you are at war. Do not underestimate your enemy (the cra's) because they will slack and sloth and not do their jobs. You must sometimes give them a nice kick in the ass to get them moving.
They simply do not care if something is reported erroneously or if you have the same account listed multiple times. They make their money from creditors subscribing to their service. They lose money when consumers dispute that information. Your not paying them anything so they treat you like a second tiered citizen.
For Example: ON transunion I had 4 seperate social security numbers listed, On experian 3 and and equifax 3.
I had items on there that belonged to other peoples social security numbers and other peoples names.
It was a pain in the ass just to sort through all the erroneous information in the start of this mess.
And then it is a pain in the ass to get them to follow the rules.
They send you canned responses that tell you nothing...even when you quote directly from the FDCPA and the FDRA reminding them of what they must do and how they must report it back to you.
You must document everything and it all must be in writing......THIS IS CRUCIAL.
You must not be afraid to take them to court if need be.
It is amazing how many stories I have read that they simply do nothing until they are served...and then it is amazing how quick they buckle.
