Terrible service

I had a lot of accounts for both myself and my businesses at Standard Bank. But their service is simply terrible. The last incident was them closing my Family Trust's account without my consent. They also changed the responsible person of the account, without consent. They changed it to the independent trustee and he has nothing to do with the Trust's banking. In fact, he has never even been in the branch where our account was held. The trust has 3 share trading accounts with Standard Bank, but we are unable to withdraw the funds because the trust no longer has a bank account in its name. I have been fighting with Standard bank for over a year to get this resolved and still nothing. So now they have our money without giving us a way to access it. The business banker responsible for the account also doesn't respond. My wife and I both lost our jobs when our company was liquidated and desperately needs the funds, but can't access it. They really don't care about their clients
