Orange County Employees Retirement System (OCERS)

I have work for OCTD and is now OCTA which falls under their credit union called OCERS during 1979 to 1985 without knowing or forgetting about this money. I found out about this retirement money when i went to the social security office printed me a copy of my earnings from 1969-2009 and it stated during 1979 to 1985 they deductions are being taken out from me and going into a credit union fund. When I question OCTA about my pension plus interest they said that I took it out. First of all, I did not take it out. OCTA cannot produce any documents, like a check that would bear my signature or the check they said issued to me. OCERS only sent me a check number they hand wrote to me on a letter.  Please assist me in this matter, I have contacted many attorneys with no success.   I don't know what to do that someone took my money for years, It is OCERS  responsibility to produce to me why this happened  and I deserve my five years pension with interest. Very much appreciated for any input you know or understand. Looking forward to hearing some educated answers or explanation for me and what to do about this matter. Looking forward hearing from anybody. Thank you and God Bless.

Respectfully yours
