ABSA *****ing from the needy and poor and hungry

ABSA just took a journal debit off my account without my authorisation. This is money my son paid into an account that I do not owe any money so I can pay rent and buy groceries for myself and my two younger children. Due to COVID I lost my job and my industry has been shut down. I cannot pay my debts right now and no ABSA too away my rent and groceries so my children and I will be on the streets with no food. How can this be legal?
