Do you know friends who worked in Germany and returned now to India/Non-EU countries?
That is a great opportunity for you to be a friend indeed. Please note that many people are not even aware that they are eligible for the refund and so they don't get this refund ever. It is loss for your friend and our country. So just ask your friend if they have got German pension /Income tax refund or not and refer them our services for hassle-free refunds.
Let your friend know that you care for him/her
