Can i get a refund please

On the 21st of August a friend of mine asked me to transfer R350 to *** using the *120*3279#. I got a confirmation that the amount was sent to account ***. 3 days ago i called my friend and asked her about the deposit since I was unreachable after the deposit due to travel commitments. The friend told me 083 number never got the money. I went to the bank as I wanted to check if the 083 number corresponds with the account number i got confirmation for so i that i can get a refund if it does not. The bank told me they can not release that information to me. How do I get the refund if that information can not be released to me even though i made the deposit. Please just refund the money into my account if the information can not be released.
