Pathetic service

All customer service agents cant help change my debit order date, i have been phoning in and no one helps. today i called again and i was told its late to change debit order date from the 25th to the last day of the month. how can it be late as it is only the 11th and after all the phone calls i did trying to change it. and i even posted a review and was told it was escalated and i heard nothing from you
