I have a - credit card ( home improvement store ). I pay regularly each month. Currently, they ask for a minimum $25.00 payment due on the - of each month. I made a $30.00 payment on the - of the month but they are not counting it as a payment for this month as toward the minimum, instead demanding that I make a payment on or before the -. I feel that I have satisfied the requirement for this month and their doing this is a deceptive business practice.
