Verizon verizon/AOL migration took all my private saved folders and personal information california

When AOL migrated from Verizon webmail I was sent a notice and was informed that NOTHING would be lost, including all my saved folders. As it turned out, ALL my saved folders were still there, but they were empty! I had evidence/email for a law suit I am going through that could cost me my house. All my registration codes that were emailed to me for software I purchased are gone! Information for websites that I manage are gone. I have called tech support and some tell me that "they are still working on it, and many have the same problem",, and some tell me "sorry, there is nothing we can do" I call again and they say we are still working on it. Someone needs to be accountable for this! I am in a court battle, paying my attorney big buck$ and the only incriminating evidence I had was taken from me during this migration! We need to unite
