Debting incorrect payments without authorization

So after last month i was sent a response that they would fix my account, it was done because i had to take this to Hello Peter. However again this month an amount of R1467.00 was debited from my account instead of R1099. I called in yesterday 28 Sep 2015 at 18:14 and spoke to one of the agents by Khahlyini Madumo and she told me i was owing multichoice and that i never paid last month, however a payment went out from my account last mont. When i requested for a manager she promised that someone would call me back. So i would like multichoice to refund back the R331 extra money debited with immediate effect and also cancel my debit order, because they are very unprofessional and hire unprofessional agents without experience, who not only make empty promises to clients but also lie.
