No response to debit order query

<p>I first e-mailed and then posted (on Glocell's Facebook page) the following debit order query : " Can you please explain why you changed the debit order arrangement on account AP 00/28/640 to go through on the 31/1/2017 and not (as per the contractual agreement signed with yourselves) to go off said account on the 1/2/2017. As there were no funds in the accounts at the time, a R115 unpaid item was incurred by the account holder. This would not have happened should the debit order have been processed on the correct date (as the required funds would have been available). I have subsequently paid the outstanding balance of R514.01 via a manual payment into your bank account (please confirm receipt of payment) and wish to recover the R115.00 unpaid item fees on the grounds of a procedural / contractual error on your behalf. " In addition to this, I have been to the Cresta branch and phoned Glocell's call centre, both of whom, could not provide me with an answer to what is a simple question.</p>
