On jan.23, 2021, we went to the coach in houston premium outlet and bought mini cally white bags, I asked the store manager near the cashier if I could get the discount for the birthday month, the manager and cashier chatted a while and they are laughing, and let me show the insider email, I opened the email and show to them, then paid the discount amount left, but when I checked my receipt which I only got 10 dollars off not 10% off for total order. I felt insulted, should this kind of person be manager? How will the customer service compensate my extra discount and give this manager a lesson?
