How Do You Get Dollar To Abide By The Law?

My daughter was robbed about seven years ago when we lived in Hawaii.  The thief rented a car from Dollar that same day with her stolen card. When we saw the pending charge, I immediately called the Dollar office in Honolulu who rented the car.  This was also reported to all credit agencies, the credit union issuing the card and Honolulu Police Department.  A month or so later, the thief returned the car and Dollar charged it to my daughters card.  We again notified Dollar that the card was stolen and were told Dollar would take legal action against her even though she did nothing wrong.  The Credit Union and HPD also confirmed the theft of the card.  Now, 7 years later, she is on a business trip and told she cannot drive a Dollar car because she owes $1,200.00 from when she was robbed.  She did what was required by law and I expect Dollar to do the same.
