BJ's Wholesale Club review: school supplies

I am a teacher and went to Bj's located at West Osceola Parkway Kissimee Fl to buy school supplies for my students and just when I was going to pay the cashier told me that I can't buy with the teachers debit card because I didn't have a bussiness account. I'm in shock because that debit card is to buy supplies for our students I don't have an store. I am a regular member of the store for two years in Orlando and never thought this could happen, I never had problem with other mega stores. Anyway after this bad experience I don't think I can renew my membership again.

Thank you,
Morales
