I opened an 18-month bank account for $1,000 as custodian for my son on March 12, 1997. I have the opening passbook/receipt received from SAVINGS OF AMERICA, FSB. An Ahmanson Company, Issuing Branch Altamonte Springs. Which branch or bank can I contact to find out if my account is still active, as that bank is no longer in my hometown Altamonte Springs.
