Mysterious deductions

<p> I noticed that in my account there were mysterious deductions done by a company that keeps changing it reference and name. I called standard to do a reversal and the call centre agent said she can only assist me with the 40 days transaction reversal, she also assured me that she has logged an investigation. She advised me that in order to reverse all transaction I have to go to my nearest standard bank branch. I went to the centurion lifestyle centre branch and I could not get any help, they also said they can only do the 40 days transaction reversal. I am worried that these people are continuing to deduct money from my account and the previous amounts have not been reversed. Can you please assist. </p>
