Addittional payment to change debit order date

Good day,<br> I called in on the 23/01/2015 to change the debit order for our subscription from the first of every month to the 25th of very month.<br> We were billed an extra R219.00 for changing the debit order date, when i called in to query the account, i was told by the call centre that this is procedure and she is sorry that the consultant did not explain to me.<br> I find this unacceptable as i would have left the debit order date the same instead of paying an extra amount of R219.00 to just change the date of the debit order.<br> I find this to be ridiculous and inappropriate. I would like this amount to be reversed immediately.
