Closure of deceased bank accounts.

Standard has been delaying the closure of an account linked to a deceased who has passed on 1 year 3months ago. Please tell me what pleasure the banks have in holding up everyone's live. It is such a small amount for a bank to struggle to pay out. It disgusts me to even think that we have to leave our hard earned money in the hands of Standard bank that can't finalize such a small transaction. Yet they will have their lawyers phone regarding outstanding balances on a credit card that was already paid off?
