Unauthorised Debit Order Amount

I called in yesterday to notify you that the wrong amount is being debited from my account. The debit authorisation form I signed in July already clearly states R300 you are deducting R500 for the past two months.<br> It is a concern that your admin staff are not functioning as they should , debiting unauthorised amounts is ******* and you are a legal firm?<br> I would like to be refunded the excess taken for the past 2 months , I have explained that I am already under debt review and in a tight spot.<br> Please contact me back with a solution to this, as per my call yesterday to your offices this was suppose to have been resolved and clearly it was NOT.
