Shocking customer service

A payment was made on the 3rd of September with my account number as the reference that was emailed to Standard bank regarding my Vehicle payment which was made on the 3rd of September.<br> I still today after numerous phone calls and at least 4 messages per day advising me that I still have not made the payment, I have discussed this and emailed the proof of payment to the *** za Yet this has yet to be rectified, Can someone with a little managerial skills get involved and contact me with confirmation that this has been rectified and that my credit name has not been affected due to the incapability's of the accounts department within your business.
