Stop and Shop complaint: Management service

I went today 31021.
I tried to purchase some food, and items at Stop Shop today. In my app I have for delivery, but, I always go to the supermarket in person to buy. The manager, named TY didn’t want to give the digital discount, because supposedly it was for delivery, she was really rude, disrespectful, and I felt she was discriminating me because of my race, because, I’m Hispanic. My husband said? Ok I’m living everything, because that doesn’t make sense that, because it said for delivery, which my wife didn’t paid, you doesn’t want to give us the discount, even though we have a card and we’re customers here, and I’m showing you the digital discount, and all the proof you wanted! She said ok, and left us hanging and embarrassing. We were standing $60 today? And had been a customer for years and spended hundreds, every month? Weekly, from $60 monthly $over $200. It was another manager there, which wanted to helped us, and talked to her, and we saw TY moving her head saying no? We’re very upset and offended by these woman, named TY!
Please fix this problem with this manager? Or I’m going to do my shopping in another Supermarket!
Sincerely your;
Ada Figueroa Pedro Ortiz
