We are having this same issue. "Melio amount change" keeps showing up on our bills and adjusting the amounts, therefore causing us to underpay our vendors. This has happened multiple times now. WE DID NOT SIGN UP TO USE "MELIO" NOR DO WE AUTHORIZE THEM TO MAKE CHANGES TO OUR TRANSACTIONS. This is incredibly frustrating and I just noticed the same thing about the reminder emails, they are coming from @qbousers.meliopayments.com...Why on earth am I getting these notifications and altered transactions from something I did NOT authorize to be in my account. I don't even have the option to disconnect the app from my account. When I go into "My Apps," Bill Pay Powered by Melio is listed, but it says "This app was connected by another user"  I've checked with all of our other users and it says the same on all of theirs as well...How do I disconnect???
