Synchrony Financial Bank Account Or Service Complaint

Synchrony Financial Bank account or service department,

Other bank product/service Account opening, closing, or management New York

I was charged a late fee of $39.00 because the payment was received 1 day late. Synchrony bank send my bill 7 days before it was due and it was paid immediately by bill pay from my bank. When I called the customer service # I was told that is the fee and that they do n't even have to send a bill by law for my loan and I should know to just pay it. The rep was nasty, argumentative and dismissive. I have never had a experience like that with a bank in my life. When I asked to speak to a supervisor I was told none was available. This is the worse bank.
