my 1st monthly bill has a billing date of 11/3/16 and a due date of 11/23/16, that only allows 20 days to pay the bill, less the time it took the bill to reach me via USPS - is this the new norm for the new billing? I would think a minimum of 30 days is allowed for bill payments. Current billing assumes residents will pay the bill as soon as it arrives. this is not always financially possible and creates a system for BCPW to charge unnecessary late fees!!!!
