Standard bank do not want to pay

My father died and left money on standard bank. We have claimed since last year with my siblings. They return us back to the court because the date was not clear and we went to get that date after that they told us the dates are not the same so we cannot get the claim we went back to the court and the court told us they cannot change the dates standard bank must pay. however till today we haven't got any answer from standard bank and it's been long overdue I really need my father's money
