<human>: Provide a brief overview of the text.

I have been working with the Peace Corps for the past two years. My parents live in South America, so I have my dad's cousin's address (Michigan) as my home of record (for the Peace Corps and other legal stuff). Because I didn't expect to be back in the States for over two years and wanted to have someone on my account for emergencies, I added my dad's cousin. Stupid decision. 

The bank that we use merged with a larger bank and got our accounts messed up (her personal account and mine). I only noticed when I looked online and saw that over $6,700 was moved from my account over to hers. I called her up and she had $5,000 moved back into my account. A few weeks later, $5,000 was taken out of my account due to a garnishment (for her, not me). Apparently (according to what she says) someone stole her identity, opened a credit account at another bank, got surgery under her name, etc., and racked up a huge amount of debt under her name. 

I haven't heard from her in at least three months, I'm guessing because she's avoiding me (ugh). 

I have the bank records to show how the money was moved around due to the bank merger and taken out due to the garnishment. Is there any legal action that I can take to get the money back? Also, I haven't been in the States since August 2011 and won't be going back until January 2014 (if that info helps at all). I have a bad feeling I know the answer, but any advice (even if personal) would be much appreciated.
<bot>: I lost close to $7,000 due to a garnishment on my cousin's debt and money being moved around by her while I was in the Peace Corps.
