Enterprise rent a car Over Charged Lakewood, Washington

On November 29, 2012 Enterprise rent a car's webpage advertised the 2013 Mazda 3 for $114 plus tax a week.  When I got down there I was charged $330 a week.  I called another enterprise rent a car and asked the rate of the Mazda 3 and they said it was $151.07 with all taxes a week.  This a very basic economy car that doesn't even have power locks.  How they can advertise one price and charge another and get away with it is mind boggling.  My car has taken longer to get repaired and so I have had the rental for a month now and each week they amount charged per week gets higher.  In another week the amount will probably be at $1000 a week.  I plan on contacting the Attorney General as well over this scam.
