attorney not giving my i-485 copy they sent to USCIS

[puru33]

My attorney lost copy of the I-485 file she sent to USCIS. My I-485 is approved now but I wanted to save a copy for myself. She had told she would send me a copy after filing but she moved to some other place as soon as she filed it. another attorney from the same law group took over the petition. now they are unable to locate the copy of file and the previous attorney didn't save it before leaving.

 Can I ask  for a compensation or sue them?
