Agent placed an order without my consent

My husband bought from a homemark call centre agent and then the following month we just saw an amount debited from his account and when we enquired we were told it was for pots that were ordered for him. We requested for the order to be cancelled and the money reversed but everyone we phone the call centre we would be told that the matter is being investigated and they would get back to us and also that a refund would be made but till to date nothing has happened. We were put from one agent to the next and all of them would take down our details and promise to call back with feedback and no one ever did. We are very frustrated by this ordeal as an amount of R2119 was taken from my husband's account without his permission or knowledge
