rude and disrespectful legal advisor

I RECEIVED A CALL FROM AN ADVISOR LAST YEAR INFORMING ME I WAS IN ARREARS WITH MY VEH ACCOUNT. I INFORMED HER I HAD JUST PAYED AN AMOUNT OF 4000 INTO THEIR ACCOUNT AND WAS ONLY INFORMED THEN THAT THEY HAD CHANGED THEIR ACCOUNT INTO A NEDBANK ACCOUNT WHICH I INFORMED THE LADY I HAD BEEN PAYING THRU THEIR NORMAL FNB ACCOUNT. I ASKED HER TO EMAIL ME THE NEW BANKING DETAILS WHICH NOTHING GOT SENT THRU TO ME. SHE INFOMED HER I OWED A BALANCE OF 39000 ON MY CAR WHICH I INFORMED HER I PAYED THE 4000 MEANING I WAS OWING THEM 35000. I PAYED THEM THEREAFTER MY NORMAL INSTALLMENT OF 1500 ON THE FNB ACCOUNT AS NOBODY SENT ME THE CORRECT DETAILS. TODAY I RECEIVE A CALL FROM SOME RUDE LADY INFORMING ME THEY ARE TO REPOSSESS MY CAR AS I HAVENT BEEN MAKING PAYMENT. I ASK HER WHICH BANK DO U USE SHE INFORMS ME NEDBANK . I INFORM HER VERY NICELY TO PLEASE CHECK HER ARCHIVES AS I HAVE BEEN PAYING THE AMOUNT TO THE FNB BANK. AND SHE SCREAMS AT ME INFORMING ME SHE WILL STOP MY CAR AND REPOSSESS IT ON THE ROAD, THE NERVE OF THE LADY TO SCREAM AT A CLIENT WITHOUT HAVING FACTUAL INFORMATION. MFC SHOULD CHECK THEIR ACCONT RECORDS BEFORE MAKING THREATS.
