Open Question: Advice neede as to next move.?

I have been trying to get all my paperwork held by my previous Accountant and she will not give me it. I have a bill from Customs from 2006 and I knew nothing about it. She has avoided me and when she called me she was very rude. I have asked her and left messages with her. I know where she lives. I have even visited her. Is she with holding my documents illegally? Whats my next move?
