SARS REFUSES TO ACCEPT RESPONSIBILITY AS FUNDS PAID INTO INCORRECT BANK ACCOUNT

I submitted my TAX return online and i needed to update my banking details. Dteails were updated and accepted and the return was confirmed on my new banking details. SARS paid the money into a bank account that is not in use but active and the account is in arrears. SARS refuse to accept responsibility as no where does it say when submitting new banking details that i need to go into a SARS office to update details, the system just accepted it and i was informed the return was going to be paid into new bank account as per ITR12 . SARS refuses to recall the money and FNB refuse to reverse the money so the bank wins SARS gets away with their scrupulous underhanded behavior where they are quick to blame the tax payer however i have proof that the money was supposed to be paid into CAPITEC AND NOT FNB . please can someone assist in the reversal as SARS refuses to accept blame and insist that the tax payer should have called.. WHAT THE **** WOULD I CALL WHEN THE DETAILS WERE ACCPETED ONLINE. I HAVE BEEN UNEMPLOYED FOR 10 MONTHS... MY MUM HAS CANCER and i need to buy her medication and i OWE people money which this return was supposed to assist me not **** me over more. Please can some one assist in trying to accept responsibility instead of just pushing the customer from pillar to post. Please can some one from SARS asssist with recalling the FUNDS and processing in the correct account as the system did not reject the bank account and neither did it inform me that it was going to pay into the last used account on Efilling- THIS IS ***** AND DAYLIGHT THEFT AS I DID NOT GIVE PERMISSION TO PAY INTO FNB instead into CAPITEC
