BAD SERVICE ON NEW ONLINE ORDER

NO BODY KNOWS WHO CAN HELP ME WITH CHANGING THE DATE FOR THE DEBIT ORDER. I HAVE BEEN TRANSFERRED BETWEEN billing departments, SALES AND MOBILE THE WHOLE DAY. I SPOKE TO ATLEAST THREE CONSULTANTS FROM ALL THE DEPARTMENT BUT THEY ARE ALL TELLING ME DIFFERENT THINGS. I APP**** FOR A CONTRACT ONLINE IT WAS PRE APPROVED BUT THE TEST DEBIT ORDER FAILED DUE TO INSUFFICIENT FUNDS IN THE ACCOUNT. I JUST WANTED THE TO TRY A DIFFERENT DATE BUT NOBODY COULD DO THAT FOR ME.
