Standard bank refusing to release funds

My dad was ****** last week and lost almost R15000.The ******s held him hostage and withdrew money form his bank accounts. After the incident he did what he knows best that is to block his accounts feqring they could rob him more.Going to the standard bank to unblock his banking systems he was told he can't unblock because his visa expired yet the government of SA gave him a grace period of until December to renew the visa.Please do something standard bank because he acquired his money legally and he is here legally.He cant be ****** by ********* and by the bank aswel!!!!
