(CNN) - Today is Holocaust Remembrance Day; calling to mind those who suffered, died and survived the Holocaust of Nazi Germany.
Nearly 70 years after millions were liberated from ghettos and concentration camps, many aging survivors are still seeking proper reparations, like Serena Rubin:
[0:40] “My pain is never gone. It’s always with me.”
Rubin and her sister Rita were barely teenagers when their family was taken out of their Romanian home in 1940 by Nazi soldiers.
After their parents, grandparents and brother were killed, they were moved from concentration camp to concentration camp ending up at Auschwitz, in Austria. Serena and Rita were liberated by the Russians in 1945 and eventually made their way to the U.S.
They’ve been working with the legal aid group, Bet Tzedek (House of Justice), to secure proper reparations from the German government.
In 2009 a German court ruled that survivors get regular pensions. But it’s not much. Serena and Rita receive about 300-dollars a month.

The German finance ministry says the German government has paid an estimated 91 billion dollars in reparations and pensions since 1951.
It's estimated that around 500 thousand holocaust survivors are still living today.
