Had a great conversation with the lead customer service rep for Chase Card Services - I called to verify acceptance of the coupon since I did not see it post to my account. I explained the process to rep and he was familiar, he stated Chase Bank has been getting inundated with coupon only payment attempts. I explained the applicable UCC code and also told him that Capital One and Synchrony Banks have accepted these coupons as a form of payment. He said Chase Bank will reject the coupon method and they need form of payment such as a check or money order. There is a separate address for conditional payments. I threatened to take legal action in federal court and he said fine go hire a lawyer. We can't do anything for you
