ACCOUNT PAID IN FULL AND DEBIT ORDER STILL RAN

I AM UTTERLY ANNOYED BY THE POOR SERVICE THAT I RECEIVED FROM PIENAAR SITHOLE AND ASSOCIATES. HAVING PAID MY ACCOUNT IN FULL,THE FIRST DEBIT ORDER RAN ON THE 25TH OF NOVEMBER, I SPOKE TO ONE OF THE CONSULTANTS WHO TOLD ME THAT THE GUY WHO DEALT WITH MY ACCOUNT DID NOT STOP THE DEBIT ORDER AND SHE WILL SEND THE REQUEST AND THE DEBIT ORDER WILL NOT RUN, TODAY HAVING BEEN PAID, A DEBIT ORDER RAN. WHAT NONSENSE IS THIS. I AM ANGRY AND I WANT MY MONEY BACK. I PAID THE ACCOUNT IN FULL SO WHAT THE F*** ARE YOU STILL DOING DEBITING MY ACCOUNT. YOUR *********** STAFF CANNOT STOP A DEBIT ORDER. NOW I HAVE TO GO TO THE BANK TO REVERSE THESE DEBIT ORDERS AND STILL BE CHARGED FOR THE REVERSE... PLEASE STOP *****ING PEOPLE OVER.. IF YOU CAN DEBIT MY ACCOUNT TODAY, PLEASE RETURN MY ACCOUNT TODAY AND DO NOT GIVE ME THE EXCUSE OF THE DEBIT ORDER TAKES 5-7 TO CLEAR... ON A SERIOUS NOTE, I HAVE TAKE TIME FROM THE OFFICE BECAUSE SOME STUPID CONSULTANT DID NOT DO HIS OR HER JOB PROPERLY...
