Hello everyone.

So my girlfriend recently applied to get a Discover Credit Card specifically aimed at people trying to establish credit (we're both fresh out of college). When she applied, she was denied the card because her SSN she provided, according to them, was incorrect. They recommended she get in contact with TransUnion as that's where they were checking the information with.

So she contacted transunion and after many hoops we were able to figure out that the SSN under *her* name is actually her mother's SSN. We've tried multiple times to fix this over the phone, faxing the documents to transunion themselves, mailing, etc. today we received a letter saying that they received our documents but were unable to determine the nature of our request (changing the SSN under her name to the correct one). 

So where do we go from here? 

I'm confused how a SSN can be linked to two different names, but again I'm hearing all of this secondhand from her and am just trying to find advice anywhere I can think of. Has anyone here experienced a similar issue and resolved it? 

Thank you.
<bot>: Transunion has my girlfriend's SSN incorrect, used her mother's instead of her own. This is preventing her from getting a credit card. What can we do?
