Deduction date

I called to correct my deduction date. It keeps on going to the 23rd of the month of the and I need it to be the 27th month. I've been calling them for for the past 3months. The cons I spoke to was very friendly and helpful. I just hope my deduction date will stay as the day I requested this time. Only giving the 4 stars because the deduction date is an inconvenience.
