Late fee on statement sent before bill due date

Hi, this is a recurring issue I have with xfinity. I have bill pay set up through my bank to pay my internet bill in full the day before the payment is due. However you send the next month's statement 1-3 days before the due date, so some months my statement says I haven't paid plus there's a $5 late fee tacked on. This happened again last month while I was very sick, the higher balance messed up my bill pay, and the payment was never sent. I have since paid my April balance but would like the late fee refunded. Also it'd be great if you stopped sending out bills before the previous month's due date. Thank you
