Stop and Shop complaint: Discrimination due to Race

I contacted stop and shop via phone regarding the policy for purchasing a money order. I was advised by a stop and shop employee Money order can be purchased with a debit card and pin not a credit card no identification required with a pin number I notified my husband of the policy, he went our local stop and shop (3106 Farrington Street, Flushing, NY, USA) to purchase money order with our business debit. At the flushing stop and shop location in Flushing NY, The cashier proceeded decline my husband requests stating an ID is needed, my husband stated his wife (Me) contacted this stop and shop prior to his arrival and the representative stated the opposite, my husband requested the policy the manager (Namoi and cashier Amit) was unable to provide a written policy that state we are unable to purchase a money with a debit card and Pin number.

10 mins later I arrived at the stop and shop location I observed a (White) individual purchasing a money order with a debit and pin number only. I asked the manager ( Namoi) what was the difference in the transactions, she was unable to provide me with an explanation. Just for the context of this complaint (My husband and I are African American). We believe that we are the victims of Discrimination due to the color of our skin.
