HOME LOAN PAYMENTS TO WRONG ACCOUNT WHAT NOW

GOOD DAY I HAVE PREVIOUSLY COMPLAINED ABOUT HOMELOAN PAYMENTS NOT REFLECTING ON STATEMENTS. A GENTLEMAN AT ABSA, FRANK, RESPONDED AND ASSISTED US TO A POINT. MY DAUGHTER HAS NOW? BEEN ADVISED YES THEY HAVE PICKED UP PAYMENT MADE TO WRONG ACCOUNT, (BUT WHAT HAVE WE BEEN SAYING FOR THE LAST 5 YEARS) AND NOW RECORDS HAVE TO BE TRACED FROM THEIR(?) ARCHIVES IN ORDER TO FIND OUT WHO CHANGED THE ACCOUNT NO. EVERY WEEK MY DAUGHTER CONTACTS THE DCM GROUP, FIRST A SHERALEE VORSTER, THEN A CARISSA ENGELBRECT ANSWER HER E MAILS AND YET NO ONE GIVES A DEFINITE ANSWER, WHERE IS THE MONEY AND WHO IS GOING TO REFUND SUCH WITH INTEREST!!!! TO HER. SHE IS GETTING THE RUN A ROUND ON A REGULAR BASIS AND IT IS NOT FAIR. IS IT BECAUSE SHE IS A WOMAN THAT THEY DISCRIMINATE OR IS IT BECAUSE SHE WONT GIVE UP. WHO DO WE CONTACT NOW?
