EFT Funds gone missing

<p>Last week wednesday I sold a car to a customer which paid me by means of a EFT from his Standard Bank account to my FNB Business Account. By Monday I contacted him to tell him funds were not reflecting. He went to Standard Bank which just said payment was made. On Tuesday he came to me saying that Standard Bank were not helpfull and we contacted your customer service which said that the payment was rejected by FNB but could not give a reason nor tell us where the funds were as it was not back in his account. I phoned FNB and they said there is no record of a "payment" or a "payment rejection or reversal" on their side". My customer has been back to Standard Bank branches numerous times but the funds are not back in his account and Standard Bank cant explain where the funds have gone. I also have a Bond, Cheque account and 2 credit Cards with Standard Bank........Unless somebody can assist us in tracing this funds you leave me no option but to close my accounts with Standard Bank </p>
