R5000.00 is nowhere to be found

On 15th July 2015 we (business partners) transferred R5000.00 from our Absa business acc to our Laptop Supplier in his Standard bank account ***3. Transaction was successful, we were told by our Supplier that he hasn't receive his money. Went to Standard bank and the Consultant showed us from her system that the account is invalid as their account numbers are 9 digits. But still Absa insist that the money went to Standard bank acc. Later I went to Absa Vaalmall looking for their Internal Ombudsman,I was told the money might be in missing fund account, they referred this matter to their Action Line Ref no: ***. Till today No one from Absa Action Line spoke to me and can't tell us where is the money
