Account debited twice

Hi, I opened an account with ABSA on the 25thof February 2015 and activated the so-called ABSA REWARDS. The consultant who opened the account advised me that there is going to be a monthly fee of R21 for ABSA REWARDS. To my surprise, I received an sms from ABSA stating that my account has been debited an amount of R21 twice. I went to ABSA Benmore branch to collect the new card and to enquire about an amount of R42 that was debited from my account and was told that it was by an error. I then asked the consultant who was helping me to reverse the other debit order of R21, and she couldn't. Instead, she picked up the phone and dialed a certain number and no one answered from the other hand.<br> <br> My concern is why is this happening and how many debit order were sent to get off from my account. <br>
