PAYMENT TO THE INCORRECT ACCOUNT NUMBER

Good morning

Please assist me with the below issue

On Friday 18/05/2018 I transferred R150 to Zithande Solutions Account ( ********** 4702) the transaction was successful. On Saturday the recipient informed me that the payment was not received, then I realised that the account number was incorrectly inserted with 1 digit but the recipient name is correct. What surprises me is that the transaction was successful with not matching details, how possible is that? The correct account number is( ********** 4702 for Zithande Education Solution).

Please reverse my R150 and my details are as per below ,I also attached the proof of payment.

I also phoned and the consultant told me that they cannot help me
