STANDARD BANK SUCKS

I unfortunately have the terrible misfortune of having 2 accounts with Standard Bank that I've inherited. I need historical statemts for SARS. I have tried since August 22 to obtain bank statements for these accounts but despite my numerous emails, and my numerous complaints on Hello Peter, I'm still waiting for a complete response. The bank has been taking off the bank charges for years, but cannot sort me out. I simply to do not understand. I have the account managers email address. I have received some of the statements but still waiting for them all. What must I do to get the service I require?
