Absa is a terrible bank

I am so ****ed at the way Absa is handling my account. How can they allow a company to debit my account without my permission and then when I ask them to cancel the debit order and send me back my money they tell me they cannot do that, I have to contact the company that debited my account. I don't even know that company and then they give me the telephone number of the company and then I called the company and the number just rings without and answer which means the company does not exist and Absa gave those people my money and how do I know that Absa is not in fact taking the money from my account, that is ***** and my own bank is commiting ***** against me. I am closing my account and I will make sure that Absa pays for what they did.
