On XXXX XXXX, 2016 we paid {$4000.00} to pay off our Citi Credit card ( last XXXX account # XXXX ) and received a interest bill for {$27.00}. Per statement and agent XXXX at Citi Bank they charge DAILY interest on the account for money owed up through the end of billing cycle and/or the time the payment is processed. The account was paid off based on their information and now they are charging us for money that has already been received by them. 

If they continue with " daily billing '' it will be impossible to pay off a credit card, if of course we paid per their billing statement. 

However, theoretically, even if I sent money and they received the money the same day as our billing cycle begins, they can still bill me interest for the hours or the day it takes them to process the payment. 

So according to their business model and legal agreement, I WILL NEVER BE ABLE TO PAY THE ACCOUNT IN FULL!
