"Yoga for the People" rude and explicit owner, Joe Young

I sent an email to Joe Young, owner and customer service representative of Yoga for the people inquiring more information about one of their yoga classes. After 2 email exchanges, in which he did not answer my question of: "what does hot yoga entail and what kind of student would you recommend for the class?"He responded with:
" Yes F*%$k off please I have real work to do" 

Has anyone else experienced this sort of explicit response from this business owner/customer service representative? I am thinking of bringing this issue to the BBB but wanted to see what other people had experienced.
