Money lost and never recovered

It's been over a year Standard Bank has lost my money and never accounted for it. I did a transfer to an FNB bank account, where the beneficiary was loaded by a consultant and number was verified. The consultant loaded the beneficiary as a once- off beneficiary without advising otherwise. I did a transfer of R13900 which did not reach the designated account, i went to the police and went to FNB to check the company's bank statement and the money did not reflect. we filed a couple of recalls but they said it wasn't possible as the account number was invalid, i have proof of the deposit and the account number and it was valid because i further did a transfer of a separate amount which reflected. Standard bank made me go in circles and up to today nothing is said and done. I advise most family members of mine to think about switching banks after losing so much money.
