Standard bank Executor-ship slow and services pathetic

Standard bank is executor of my deceased husbands estate which was closed 2009 and recently I received a surplus benefit on his pension and have asked standard bank to assist because they are the executors. its has been over 6 weeks that Standard Bank have been sitting on this issue and each time I phone there is another excuse ranging from power outages to files not received and have been passed from person to person. I am a 72 year old living on a state pension and in dire need of this to be settled as soon as possible with out excuses.
