Sorry, to hear about you having that happen. I've been there... sadly it was a family member who took out a credit card in my name and racked up almost 10k in charges while I was in college.
I contacted all the credit card agencies and had a fraud alert added to my accounts. I had to prove it was me anytime a credit line was applied for and credit checks couldn't be made for 6 months I believe??
I love that you can now get your free credit report yearly, and still check mine. I think everyone should!
Bleh, its so time consuming going through all that. Glad your bank is taking care of those charges for you
