Account issues

Called the call center twice in July to change the Dr order date from 25th of each month to the 1st or at least the last day of the month since my salary date has changed. Both agents were not helpful and the 1st agent was rude and said I must speak to their legal dept and then hung up on me. The 2nd agent wasn't rude but, still not helpful as she advised that their Dr orders only run until 28th of the month. That still does not hep me as I am getting paid on the last day of the month and the bank is charging me for the unpaid early Dr order. Kindly assist
