Business ProfileforNetCost Market

I took my senior citizen mom to NetCost in December, before the holidays. This is a time of year when a lot of food is involved. From the caviar, to desserts, and many other food items, we spent $700! This is a lot of money for any person to spend but especially a senior. The reason we went to netcost is because they offer a 10% senior citizen discount. On this trip, we were asked for my mom's phone number (to confirm her account and age) and provided it both at the caviar counter (you have to pay for it separately) and again at the register. I asked the cashier if she was able to find my mom's account so we could get the 10% off (roughly $70), and I was told "yes." Once we were done shopping, I noticed that the senior citizen discount was not applied to any of the receipts. I came back to speak to a manager and was told that she was out. I asked to return all of the merchandise and repurchase with the discount but was not allowed to do so because it would take too long. I was assisted by a lady who called a customer service number and both the man on the phone and the lady in the store ASSURED me that I will get a call from Steve and that my issue will be resolved. I did get a call from Steve. After a long conversation was told "there is nothing we can do, you shouldn't have left the store." I told him that this was a total bait-and-switch and asked to speak to his supervisor. He said that he is the head of the department and there is noone above him, he also said that I am not owed anything, and that they can change the policy at any time, as they please. I pleated with him to do something, give me a store credit, or anything! He said he would see what he could do but that I probably won't hear from him until the holidays were over. Now it's the end of March. I tried calling again and left messages. I have been a client of NetCost market for 12 years. I didn't expect such a large chain to treat their clients (and especially the elderly) in such a terrible way.
