Bad customer service

I paid my vehicle instalment by stop order (directly from salary) on the 21st of December 2015 - the amount of R3200.00 but I forgot to write the Wesbank account number as reference<br> The amount did not show on my statement obviously because I did not put the reference number on the instalment paid. I called Wesbank and spoke to an unfriendly consultant who said I should send an email. I sent an email and the response was for me to send: date of transaction, account number used and reference used which I did but was advised that funds could not be located.<br> the stop order even reflects on my payslip that It was paid into wesbank's bank account. My HR intervened but Wesbank still could not assist. I need the funds refunded back to me as I fail to understand how Wesbank can be unable to trace funds as the reference I used couldn't have been used by a million on their clients who paid debit order on the same day I did. someone is not doing their job here. I cannot just lose money like this - <br> <br> Something must be done to locate the money. It cannot be impossible to locate funds just because there was no ref number. <br>
