Blocked Account/Poor Communication

I am so disappointed with their service. Standard Bank decided to block my account without any communication. I buy and sell crypto currency so im always getting large amounts of money sent to my account and I have made that clear when opening the account with them. I have been emailing and calling regarding the block, but each time I'm told the investigators will get back to me soon. It has been 3 weeks since the block, and nothing is happening, I've sent the documentation that they requested, but I am getting no help. Even my mother's(Edwina Hill) account is blocked, and she also does what I do. Standard Bank sent money(R17000) out of her account without communicating with her, she is so devastated and heartbroken, when she spoke to consultants they told her there is nothing they can do about it and will get back to her. This is really insane. If I knew this was the service I would be getting I would not have joined this bank.
