I just got off the phone with the bank who I finance my car through to ask to split up the payment for today and next week. She got the biggest attitude with me saying how its not a payment arrangement it's a note. I want totell her that splitting up one bill through out the month and promising to pay on those days is called a payment arrangement. She told me like 3x how it's a note not an arrangement because I kept saying arrangement. All I said was oh ok st the end and thank you. Lol. Weirdest conversation with a customer service person I've ever had
