When I checked my TransUnion credit report, addresses listed for me included XXXX I had never lived at, although my daughter and her husband had lived at XXXX some years back, and my son had lived at the other when he was in the XXXX, again years ago. I disputed the errors online. Sometime later I got a form letter in the mail stating " Here is the ... report you requested. '' They had removed XXXX address, but not the other ... no explanation why, of course. I tried to dispute online again, but for whatever magical reason, their system would n't let me. So, I downloaded the mail-in form, filled it out asking them to please remove the incorrect address, and also included a copy of my deed with a request that, while they were at it, could they correct the date at which I moved into my current address from XX/XX/XXXX to XX/XX/XXXX. Some days passed and I got a copy of the same credit report in the mail, no changes, with a form letter stating " Here is the ... report you requested. '' No mention of the dispute. I called their contact phone number. I asked that the incorrect address be removed ( I abandoned trying to correct how long I have lived where I live ). The representative said the error would be fixed. A few days later in the mail I got the same report, same form letter. Acting like an idiot, I called again. Again I was told that the erroneous address would be removed. Guess what I got in the mail today? This is a very simple problem. They ca n't fix it. Yikes!
