I am new to this forum. My society issue a building repair work invoice on 15th of every month asking its member to make a payment by same month end. Now for some reason I delay a payment by one day which is payment was suppose to be done by 31st but I made a payment by 1st of next month. Now society is calculating the interest for complete next month which is for period of 1 month and charging me. My question here is can society or any one charge me interest for complete month when the payment was made on very first day.
If yes which rule are they following. I know this amount is not big but just want to know is this behavior right.
