I made a contract with them because I saw John Foy & Associate on their website that they deal with car diminished values. However after I made a contract, The case manager told me that they are taking care only personal injury. And today she asked me about past accidents and asked if Diminished Value of car has been paid. I don't care the past accident. Because All are not same. and also I learned about Diminished Value of car on their website. If she dosen't want to handle my diminished value of car, That's fine. Please change the case manager. She is not profetional very much, and she is so rude.
I'm so dissapointing to John Foy & Associate. I'm thinking I chose the wrong law firm.
