Constant Harassment by Standard Bank

I paid the required amount for my vehicle on 1st September 2015, it is now the 9th of September but I am constantly getting messages from Standard Bank saying that they have not received my payment even when payment was made on 1st September.<br> <br> I am extremely annoyed with this constant harassment from Standard Bank even though I have paid. In addition this will now reflect badly on my credit record because it will show that I did not pay, when in actual fact I did. Doesn't the bank actually check who hasn't paid before they send out sms requested payment, which in my case was made 9 days ago.<br> <br> Should this harassment continue any further and should my account not be updated accordingly, I will take this matter to the credit Ombudsman.
