Standard Bank will kill my motherwith their negligence

Worst service ever, had a payment come through in my account and account was blocked this was on Monday I quickly went to the bank and they asked me to submit documents that are proof of funds and I did so that same. Monday the lady at the branch emailed them to Harry Mabokela the investigating officer responsible for blocking the account, the person does not seem to respond to his emails nor answer any calls its been days this has been happening and the worst part is these funds where meant for a operation that my mother has to go through on Wednesday and already its Friday have sent countless emails, tried calling from the bank they just don't respond now my mother might lose her life because someone decided to block an account and not even attend to his emails, even the other people I have sent emails to in transactional ***** they open and do nothing about it. If my mother dies I will do everything in my power that standard bank pays for this. Yesterday the doctors advised that her organs have deteriorated so much that we might end up failing to do the operation. Is there anyone who can help
