On using Chase Pay, I had the Staples offer on my Freedom for 30% with a Max of $19, did a purchase at Staples and neither the cashier nor the store manager knew how to use or scan the code on my iphone, and for me that was my first use too, they had a scanner for apple pay which the manager tried but did not work, so ended up paying with the card by inserting the chip, will i get the credit of $19? How to pay with Chase Pay? Is Staples not equipped for it or they just did not know how to use it?
