Impossible to capture a debit order!!

When I changed jobs, I changed my debit order with Sanlam because my previous employer paid my annuity as part of my salary package. <br> <br> I received an email from Sanlam to inform me that my debit order has been changed.<br> <br> On the first of February they deducted, wait for it.....R24,373.36 from my account! Yes, as in more than twenty thousand rand! The inconvenience I cant even begin to describe! Sanlam said it will take a few days to transfer the money back to my account. I had to take off at my new job to go to the bank, sit in a queue and reverse the transaction on my own.<br> <br> The next month the debit order went of as it was suppose to but I received an email to say they made a mistake and did not change it at my previous employer so I have to pay double.<br> <br> This month they deducted R1350,00. I don't understand the maths because my installment is R450pm???<br> <br> My broker suggested I wait and see what happens end of the month. My gosh! That means they can deduct anything between twenty four thousand or four hundred and fifty!<br> <br> How pathetic that Sanlam cant capture my debit correct! Every month is a frustration !!<br> <br> Very disappointed!
