I have a father or who has just passed away almost two years ago, if I know I was in my father's last will and testament and even my father's lawyer

Continued; seems like he is very untrustworthy to the situation and since he has passed the company he owned and everything he owned dissappeats and I'm being and have been completely shut out and denied anything even temp access to his things (even simple things) for the pas years since things got like they are, what do I do? And I've tried contacting lawyers or etc in my current area and it seems really hard to even get through to one and almost feel like I am being shut out everywhere I try to get help.
