Standard bank not using technology so they can rob the clients

I recently sent a Email through the banking app where they promise to be in touch within 24hrs.two emails and 4 days later nothing happened. My account was deducted by R 132. Fora shortage of R 29 on a debit order. They have the technology to inform the clients about everything but will not inform before processing the debit order. the reason being that they want to rob the clients of they're money
