Nedbank Cullinan Diamond Mine

I have been trying to pay an investment out for my son schooling, my mother opened it who is now passed away. Last year I needed an unabridged birth certificate ( Home Affairs have lost my documentation) but now my son is eighteen they have changed the rules. My next step is to take my mother's ashes into the bank. This is ridiculous. Can anybody with an ounce of logic contact me on ***
