In all my life, I have never--before this month--received a bill that FAILED to show the previous month's payment received. That info must be on any invoice or statement of account: to show what was owed the previous billing period, the PAYMENT THAT WAS MADE and the new, current or total balance. Your invoice designers were so focused on showing comparables that you completely forgot or left out the amount that I PAID. This is very frustrating to me as a longtime customer.
THERFORE--PLEASE INCLUDE THIS INFO even if you have to hire new people to re-design the page again!
