AXA Equitable

Well my dad has been paying my life insurance for me since I was a kid so I had a policy with axa. Then my parents both had separate policies with axa. This is were it gets tricky, everything went smooth when my mom passed death policy was paid nothing wrong. But when my dad passed oh that's a different story we are 4 kids one was not there and the other child fraudulently signs his name right in front of the axa agent with no problem and he handed over his portion of the death benefit to my brother. So is that being screwed over or what. To me that's fraud fraud no way how you describe it it's fraud and i'm still here fighting with these idiots for my money. What's rightfully mine.
