My mother was a client for years since she was diagnosed with cancer and she passed away not too long ago, so I was trying to become a client on her behalf, but recently I received a notice that they were closing my case because I wasn t able to send them papers as fast as they wanted. I work full time and obviously had a lot going on with the death of my mother. I was told in the letter to go find another lawyer, but they have all of my moms info, and medical info so I am upset that I might have to start this process all over again.
