Am I being discriminated against?

A local scuba diving shop in my area - manager is a white female. As an Asian female, she treats me differently than all other customers. She has been half as friendly to me, when comparing her service with the other white female staff/customers. I have been there for 8 months, buying over $10,000 in products, never paid late, have an excellent reputation at the shop with all of the instructors and staff. I bought an item for $1800 and she refused to help me alter it, with NO explanation. I had to work through the shop's owner to get what I needed. My spouse paid to take PADI classes to be on staff for an instructor. Now he's denied this service, and not told why. He has been given very high grades and passed the classes with flying colors. With NO explanation again, she told me she wants the store to "end it's professional relationship with me", deleted my spouse and I off the shop's social media accounts (where shop specials and staff announcements are being made), refused to let my spouse and I attend group events she organizes, and made a public announcement to her staff that my spouse and I are "no longer in a relationship with the shop". I feel as though it's my race??
